Basically the day you lose your childhood innocence. You become to old to have fun and people start expecting shit from you. You become a teenager. Your parents realize you’re not their precious baby anymore so their tone towards you changes. You turn from a kid to a teenager. Your 13th birthday is the day you lose your childhood and start getting treated like a grown up. To all you twelve year olds, trust me, it’s not that great, all of us 13+ kids would love to go back to our childhood.
Your 13th birthday is the end of your childhood and the fun and innocence goes right away with it.
