Why do people have to be vague when they could be clear?
Like when someone asks a question and the reply is "once or twice". Well is it once or is it twice? Surely they know! Just answer it. Fair enough if the answer is 20 or 25 times where there is real doubt and maybe the person can't remember, but if the answer genuinely is "once or twice" then they must know whether it's once or twice! If they really don't know and it could be 2, 3 or 4 times, just say "a few". It gives the impression that they're trying to avoid giving a true answer and are deliberately being vague to hide the truth.
Another similar one is when someone says "no less than 2" - well just say 2! That comes out a lot in the house hunting programs where the presenter will often say proudly "no less than 3 bedrooms" or "no less than 2 bathrooms" - just say 3 or 2. We all know they don't mean 4 bedrooms when they say no less than 3. It's just words for the sake of talking and drives me nuts.
