What is the one (or two) quality(ies) that annoy(s) you more than anything?

If you can single out those things. For me, hypocrisy would be number one. I absolutely cannot stand it and I will not let it go. I will fight against it with everything I have. Arrogance would be #2. And no, by saying this I am not saying I have never been hypocritical or arrogant. Those are just two things that I truly hate.
