...very very angry ... is when people use the term 'meet up' and 'wait up'. I dont know why but these terms are like chalk on the blackboard to me.
I decided to meet up Mr X .... I mean whats wrong with ... 'I decided to meet Mr X.'
And if I am not mistaken its a term I've heard from girls only.
I dont know if somebody else also gets as irritated as I get on hearing these terms.
