Ok so my pet hates:
1) nail biting or any slurping/nibbling/clicking habit!!!
2) filling up with fuel (takes so long, costs a lot) complete waste of time (apart from the fact that couldn’t get from a to b without it)
3) being let down, if you aren’t going to show up or do whatever you’ve promised don’t say yes in first place
4) people who drive round and round car parks- just park!
5) toothpaste on the mirror
