I really think that, as humans, our perfection lies in the so many little imperfections that make us different and unique. Among those are our habits and fears.
I am terrified of balloons! The sound of a balloon being blown up makes me jump up and hit the ceiling! Also, bees, maybe coz I've never been stung by one?
Bad habits: here's a nasty one: I'm a heavy smoker. And I nibble, not my nails, but the skin around them (I know, Yuck!)
So come on, let out the dirty secrets ;)
