It depends, I used to just try to shrug it off, but people are usually pretty understanding if you just tell them what it is. Unfortunately sometimes people will just start asking you a ton of questions. I don't really mind the questsions, so it's not that big a deal to me.

i suggest what archy said if you don't mind people knowing. although if you DO mind i can say a few things:

if it's a head twitch, just kind of...work it into things... like...if you shake quickly, do that and then stretch your neck so it looks like you were just stretching.

i can't say much for vocal tics.

but for ever physical tic, just work it into whatever. whatever it is...find a way to make it look like a stretch or a itch or whatever.

hope that helped :)

My daughter has many physical tics that she molds into every day movement and most teachers say "I dont see her tic but she stretches and cracks her back a lot" --> all tics but molded into something people are use to seeing.. as for vocal, my kids try not to tic vocally at school bc of fear of others.. most tics they arent able to hold back on.. I dont know what to say for the vocal ones.. My daughter gags and hummmmms all the time.. my son clears his throat and they both whistle so.. when people ask why they do it, most times they say its a tic and keep moving on and will go further into details if someone asks what a tic is.. sometimes just saying its a tic stops them from asking.. Good luck.
