Paper cut
I just poked myself in the eye, when I put on my glasses. What's your "I hate when that happens"?
When I drop something multiple times. Seems that my hands aren't listening to my brain.
I hate it when I set off to do one tiny little thing then get side tracked doing a million other things and completely for get to do the first thing I set out to do! (It's one of my problems in the kitchen! Grrr.)
Stubbing my toe. I'm a klutz, it happens often.
When I'm climbing down a ladder and completely miss the last step.
I'm with Hippy on this one. When I pick something up. It goes right through my hands and onto the floor.
