What annoyes you?

What annoys me!

Don't you hate those days where you get those bad days where you just can't be bothered doing everything, yet you have obligations that need to be fulfilled.
I'm sure with some things we can all agree, and here are some things that REALLY annoy me.

1. Don't you hate it when you're in a line waiting somewhere and somone comes in very late and the next thing you know is that they are the next person in line while you have been here waiting for more than 1/2 an hour.
2. Don't you hate it when you're busy chatting about somthing important and somone (i.e. little brothers) taps you continously on your shoulder saying something that can't wait to be said.
3. When you're running late and while driving are trying to avoid as much traffic as possible so you take the detour and you come across a big traffic Jam and theres nowhere to go and nowhere to move and apart from that you have to wait for ages and the line doesn't even move.
4.When the weather changes and one minute your very hot and the next your really cold, especially at night when your trying to sleep.
5. When your enjoying the sun having a bbq during summer and the flies keep bothering you trying to land on your face, or bothering you while you eat.

any other ideas leave them on the comments area either agreeing, disagreeing or new suggestions.
