Flash photos... at a movie theatre.

went to the theatre earlier to watch dog man. (please go watch it was peak) and i saw some girl who was on her phone the whole movie. was fine at first, maybe she didnt want to watch the movie and her kids forced her. She looked to be about 19 though, probably too young to have kids. she then started taking flash photos while in the dark room, while making a tiktok or something. wasn't super annoying, but she was still taking flash photos while in a movie theatre.
