"... a nice young man to introduce to my daughter (age 25)"

sure... I got a son age 27....but 'nice' seldom means 'compatible'. His interests and habits would be odd to some, even though folk music is now one of them.

I know people of both sexes who are perfectly decent, interesting people, but who have little things that keep them from 'meshing' well with most others in any living together arrangement.
