School events can be a great way to make new friends and hang out with other classmates. Typical school events are sports games (especially football) and dances. It's good to go to a few of these to have the experience and show your support for your school, but going to every single one isn't essential to your high school experience, despite what most people will tell you. If you're a little antisocial like me, going to every single football game isn't the top priority. The whole point is to have fun with your friends which doesn't necessarily have to be done at a school event. The fact that you went to prom isn't as important as the memories you made there, and just going over to a friend's house can be just as worthwhile so don't feel pressured into attending every single school event.
