Do you find yourself saying 'Nice to meet you' or 'Nice to see you'. I have always said 'Nice to meet you' but I have noticed a lot of people say 'Nice to see you'. To me, that doesn't make sense. That is reserved for encountering a person you have already met after you have been introduced.
Perhaps I am alone in this. I was just curious which of these two things (or perhaps it is something different altogether) you say?
