I accidentally kicked some guy in the nuts and he cried and ran away. I don't know what to do?
Did you apologize?
He ran away before I could.
Probably a good philosophy to live by: Don't kick people in the testicle for no reason.
He probably wants revenge.
You're going to have a hard time explaining why you kicked him. He might want revenge, or he might accept your apology if it's sincere. I hope you learned something here.
