Today was the second time in the past few weeks that I have been described as shy by new acquaintances. I believe I am calm and collected and choose what I say carefully. I don't get involved with gossiping or anything like that, so when the conversation turns that way, I usually sit back and just jump in for some wit or humour. So this might be the cause.

Does anyone know the differences in characteristics between someone viewed as shy, and someone viewed as calm and collected?
