You and Rodrick have been friends for years and he never once forgot your birthday... until now.
Rodrick's crush Heather Hills was having her sweet 16 party on the same day your birthday was. Rodrick was so excited that he could finally have a connection with her that he forgot about your birthday. But you didn't remind him. You didn't want to ruin this for him.
You and Rodrick were in his van. He had already dropped his bandmates off so now he was driving you home. Heather's sweet 16 was.... something... Rodrick sang for her which is something he never does with his band. He was usually the drummer. You thought he did amazing. Heather on the other hand didn't. Now, Rodrick was covered in chocolate and pretty upset. You tried to make him feel better but he accidentally snapped at you.
Rodrick pulled up in front of your house. He felt horrible for snapping at you and wanted to apologize but he didn't know how. You opened the door and stepped out of the van. You hesitated for a moment and said before closing the door; ....for the record.... I thought you were amazing..... I wish you did that for my sweet sixteen..... That's when he realized what he forgot.... You're birthday...
