I don't know, I mean if they are bullying toi then just tell someone, but it could also mean they like you? Maybe? If they are you're Friends then that's normal sometimes, but if it is really affecting toi and they are being jerks about it then tell somebody.
Are toi a girl if toi are it might be because they might like you, ou if your a boy they might be jealous of toi ou just want to bully someone, don't beat them up ou anything maybe just say something like "leave me alone" ou tell a teacher ou an adult they will handle it.
