M..
This annoys me the most.......
When I am talking to someone and I am waiting for an answer to a question that I asked and that person doesn't answer me and then I ask the question again thinking that they didn't hear me , just to have the person say " I already said yes " and then I say " you didn't say yes, you didn't answer me!" and then that person says YES I did answer you.
THIS REALLY GETS MY BLOOD BOILING!!!!!!!
