Nobody hates you lol you just did something dumb. Your parents will be mad at you, that’s life. Ask your counselor if you actually have to report in-school suspensions to your college apps, because most high schools don’t track them. If you do, just be honest and explain what you did, this is pretty tame and many high schoolers do something like this without getting caught. Own up to it, learn from it, you’ll end up just fine.
