Ah, that's nice of you for helping the coaches kid out. But yeah, you're right. I shouldn't let that get in the way of my day. Thanks for the encouragement.
You know what you should do? Once they start bullying you record the audio with your phone. Proceed to tell an adult and when they say YOU bully them, show the adult the video.
I think i'd be the kind of guy who would tell my kid to say this to a bully: "Well, im ugly? bOy you look like you eat 15 bags of party size cheeto puffs a day, I think you get your saltiness from there. And don't even get me started on your looks, man you look like you have a lazy day every day. And look at that haircut-"
