The humming one you did at 2:44 is the same one this girl in my choir just started doing followers by this quick "ha ha ha". That's why I looked into it, it's strange tho bc she didn't do it last semester and I've always been near her on the risers. I was kinda annoyed at first thinking it was on purpose/ to distract is from singing bc we have a competition coming up, but then I researched and found your channel. Thanks for being brave and posting these videos and also for informing those like me who don't tic 💗
