Random habits of mine

I'm discovering that the more stressed I get, the more random habits I develop. Not that I didn't have plenty to begin with:

• I never get into the shower and then turn it on - I only ever step into running water.
• When I switch pens, I don't put the pen I'm writing with down, I hold it between my teeth.
• I cannot stand to have one hand wet or greasy or slimy and not the other. Not that that's usually a problem, but it does happen!
• Currently when I sleep, I do so with my arms between my legs, crossed, so that each palm pushes against the opposite thigh. I'm also completely unable to sleep without some kind of pressure (duvet is best!)
