yeah now I remember. stadiums holding 5000 people. they don't let people go. interesting.
but still sometimes we, nonnatives, become like robots who can do anything a human does but don't have emotions. we say something but are by no means aware of its full connotations and always wonder what a native would say in that particular situation. a foreign language is like an uncharted territory in which we can never be sure when we will step on a mine. this is true of nonnatives, at least for those of us who have not lived in a country where English is the medium of communication. but you natives help us very much in the right direction. thank you very much indeed.
