A boy has been done for sexual assault and it's all come back to me?

Honestly, you shouldn't care, its yours, your friends, and that boys Business not theirs. Let them talk, it shouldn't matter what they have to say. They're obviously ignorant and immature and not worth the energy or time. You shouldn't care if they talk bad, because honestly it doesn't matter, just separate them from you. You're in a different grade and can find someone in your own grade. So just let them, if it starts getting serious, you obviously need to let let them know what really happened, but either than that don't waste your time or energy on it. it's just stupid and should blow over soon.
