Expressions

It seems quite a coincidence that having been writing and thinking about sayings during the last few days, a programme on our local radio station this morning was getting people to ring in with expressions, phrases and sayings they dislike. One that came up was “I can`t get my head round it”, along the lines of how can one literally get ones head round an object. And, what a lot of contradictory expressions people use when you think about it – like “awfully pretty”, surely something is either pretty or it`s awful but not both! And using a string of words instead of just one – like “at this moment of time”, instead of just saying “now”. Why do we do that?
Our language is a strange thing isn`t it?
Wonder what expressions others dislike or find inappropriate.
