If it is a scary film I cover my ears, shut my eyes and start humming.
If it is a job interview I wast to smoke a lot, but then who wants to employ someone who smells like an ashtray? That just makes me want to smoke more....
If I am at home and awaiting bad news, or stressed or anxious, then I clean - I start with the washing up, move to cleaning the sides down, then I get the mop bucket out and everyone knows to steer clear and keep outta my way!
Apologies, for the short answer earlier - my boss snuck u[ behind me!
