I like to break out into a song and/or dance at random times.
To avoid agruments with my husband, I make goofy faces. I swear it works every time. I hate arguing.
I do both of these things. The funny faces bit does NOT work at all with my very serious German husband. It works on my goofball son, though.
I talk to myself in the garden. Mostly begging the bees not to sting me, or explaining to the plants why I must move them around. I used to talk to my experiments in the lab... everybody always told me that this made me certifiable.
I shout at lampposts.
So do all the crazy homeless people in San Francisco. When they shout at
me, I shout at them back. Pretending you have Tourrette's is like, totally awesome!
