What is the funny habit you have ??

i used to start giggling when i was younger and whenever my mom was in the room because she would catch it from me and we both would start laughing for example when i had piano lessons i remember and one time we were at this serious performance and we could not stop laughing it was so embarrassing

Turning on a light switch while knowing full well the power is out.

Me too! The worst was at a funeral :(

Adjusting myself when I think I'm alone... but I'm not !!

Start dancing when I'm alone.
