Redundant Words

Isn't it amazing how people use redundant words and phrases or ask redundant questions, and don't really know they are doing it? When people look at old photographs of themselves which were taken years ago and ask "Was that me?" when they know very well it was. Years ago, a friend of mine phoned up. My mum answered and said hello. She told me who it was and when I put down the phone, she asked "Was that so-and-so"... I replied, "Well you have just said hello to him, so yes it was".
