Am I Petty/Selfish?

It’s my fifteenth birthday tomorrow but all my family is coming over today to celebrate. I’m kinda feeling upset because my parents didn’t ask what food or cake I wanted like they do other years, and when I asked if my best friend could come over my parents said no, even though she’s come over in other years. Am I just being a typical petty teenager being upset over this, or do I have a legitimate gripe?
