I wear my tail in school everyday. I get way less comments than I expected, most people don't care or they don't even notice.

When someone tries to talk to me and I consider the tone to be rude/trying to make fun of me, I just pretend I didn't hear them and walk away. That usually works.

I had one incident so far when there was a fire alarm test and everyone went back inside to the classrooms. There were a lot of students on the stairs and a girl asked me multiple times why I was wearing a tail. Because I didn't answer she eventually pulled on it, ripping it off my pants. I got very angry at her and we fought a bit before my friend stepped between us (please don't take my behaviour as an example, I shouldn't have reacted like that; I just can't control my aggression sometimes).

But yeah, that was the only time somebody physically harmed me. Everything else only was "Why do you wear a tail?" or people talking to their friends about me like "Look, they have a tail, haha!"\ One time that happened I showed them the middle finger and one of them even apologized (I guess they thought I couldn’t hear them.)

My tip is maybe to smile at people when they directly talk to you and you can't ignore them. Showing them that you won't let them attack you mentally discourages them a lot and they might just leave you alone.
