Do you ever have a compelling urge to throw your wallet or keys into the water when you're near a river or lake? Like a little devil on your shoulder battling against your common sense. I was relieved to find out from a friend that I am not the only person who has this. There must be a word or a term for it. Very odd. It's a bit like the (un-suicidal) urge to jump when standing at the top of a tall building, or at the edge of a cliff. This discussion suggests a link to Tourettes Syndrome.
