Why is it when.......

[TheDetailDoctor]

You have one of those really annoying sgaggy finger nails that keep catching on stuff, every once of common sense with you is saying "DON'T PULL IT", but for some reason you still pull at it.

I've just had one of these moments and the bloody thing hurts like st & won't stop bleeding now.

I know this one...

This is up there with when you bite your cheek and then continue to catch it every time you chew for the rest of the day!!
