My pet hate is when people ask you a question, so you reply, but they were not listening anyway, then ask the same question again about five minutes later.
My hubby is always doing this to me. Why ask me a question, if you aren't really interested enough to listen to the reply??. That really drives me mad.
Another one at the moment, People that say "Inn'it" after ever sentence..................omg what is that all about??
How thick do these people really sound, when all the say is " I went to the shop Inn'it".........grrrrrrrrrr

.
Another one, people who whinge relentlessly about something for weeks, but don't do anything about it. If it is getting on your nerves that much, just change it, or shut it!!!!!!.
