As the years go by Chapter 1

Chapter One: Goodbye
Phineas looked around the yard and smiled proudly at his stepbrother's and his latest feat. Phineas had noticed over the last few days of the summer that Isabella had begun to look sad. After noticing that, Phineas had begun planning his surprise for her. He'd told all of Isabella's friends about the plan and they had shown up bright and early to get it all ready. The result: an amazing cheer up party filled with all the things Isabella loved. After working since before sunrise, they had finally finished; all that was missing was Isabella.
"I'm going to go get Isabella" Phineas told everyone "You guys get this party started"

Once he reached Isabella's door, he rang the bell and waited. After a while, Isabella's mom opened the door.
"Hello Phineas, what is it?" she asked him
"Afternoon, I came to get Isabella; we're throwing her a party at my house. Tell her to wear something special, but don't tell her about the party" Phineas said
"Of course, come on in, Isabella's still upstairs, I'll go tell her" she told him and led him inside

Isabella stood up and opened the door for her mother. She was smiling happily as she walked inside.
"Phineas is here to see you, he told me to tell you to wear something special; he has a big surprise"
Isabella looked up at her mother and smiled, but after a minute her smile faltered. "Mom, I haven't told Phineas yet…" she trailed of sadly looking at her stuff all piled up and ready to go.
"But I thought you told everyone of your friends"
Isabella bit her lip "I told them all, except Phineas... I just couldn't bring myself to tell him"
"Tell him today, now go get dressed and have some fun"
Isabella looked down the stairs to see Phineas calmly waiting for her.  He looked great, with an orange T-shirt underneath and unbuttoned white shirt, and deep blue jeans, he looked even better than usual. Isabella smiled as she walked down the stairs.
Phineas looked up to see Isabella coming down; he thought she looked great, wearing a white bow with a dark blue dress. Once she got downstairs, Phineas took her hand and led her to his house. Isabella looked so happy and surprised she even hugged Phineas tightly and thanked him for everything.
The party went on great, Candace and Jeremy spent the whole night together, Perry didn't mysteriously disappear (he had a day off), and the stepbrothers' parents had, for once, actually known about the party and had been there all day. It was around sunset when Isabella decided to tell Phineas. She touched Phineas' arm lightly
"Could I talk to you in private?" she asked him
Phineas nodded and led Isabella inside to the empty living room. Once they were seated on the sofa, he turned to her, a worried frown on his face and asked "what's wrong?"
"I'm leaving" she told him sadly
"You're going on vacation" Phineas asked puzzled
Isabella shook her head "Leaving to Mexico, we're moving there to help our family. Mom said we'll be there for a long time" She took a deep breath "We leave tomorrow, I have to go, I tried to convince my parents to stay but no luck" Isabella looked down and shed a single tear. Phineas immediately wiped it away and hugged his best friend; his eyes were full of tears.
"I'll miss you Isabella, but I will never forget you. I know that you will come back someday" he told her, looking her directly into her eyes. He thought he glimpsed some hidden emotion, but it was hidden away again before he could be sure. He went on "we can write letters and postcards, talk on the phone and send pictures"
Isabella nodded, she wanted to tell him how she felt, but it made no sense to tell him now, when she was about to leave and would be gone for a long time. Instead she looked at him and smiled "Let's go to the party, have some fun before I have to go" she told him
Once the party was over, Isabella said goodbye to all her friends. Phineas walked her to her house, after one last hug, Isabella went inside.  The next morning at the airport, Isabella got the unexpected surprise to see Phineas there. HE was holding something behind his back.
"Isabella, I made this for you last night, it's a photo album with pictures of us and our friends; I got everyone to sign it. I also made you a copy of all the songs we've made this summer and last summer and on Christmas" He told her with a smile
Isabella hugged her friend "I left two presents for you by your house" she told him
"I saw them; I'll take care of your dog as if he were my own. And I loved the other present too"
"Flight number seven to Mexico City, boarding now"
Phineas hugged his friend one last time before letting her go. He craned his neck to catch one last glimpse of her as she left. Once she was gone, he carefully took out her gift from his pocket. It was a picture she had taken the day they made a romantic cruise trip for Baljeet, she had signed it, he read the words over and over 'I'll always be with you and I'll always remember you, never stop being who you are. One day I will be back, love Isabella.' Holding the photo close, he got to his house and framed it, putting it on the night able. He lay down on his bed and whispered to the ceiling "one day I will see her again, and when I do, I'll tell her"
