Everyone has one. That is a pet hate. Something that makes you reach boiling point, or too quickly over react.

I confess to two, which I'll lump as one because they are similar.

Litter and litter louts, along with untidyness (I can be untidy myself until I feel guilty enough to come to heel)

The other one I feel strongly about is waste, and that is waste of anything, materials, food, talent and particularly the waste of the most valuable thing there is given to us, and that is time.

There you are. I've got those off my chest. Someone else's turn to have a bitch about things.
