The pencil issue!

My colleague, Cassie, today confessed that when her husband, Rob, comes in to pick her up from work he always turns my pencil round. Now this would be a huge concern if I had OCD but it turns out that every time I turn the pencil back round and didn't even know I was doing it! I'm sure he'll move onto some other subtle mind game now the cat is out of the bag with this one!
