Dealing with old people

I have been pursued by a man in his fifties all week.  I finally had to tell him I am neither attracted nor interested.  I am open to meeting someone closer to my own age with whom I have something in common culturally, intellectually, etc.  The guy never made any space for me to introduce myself.  When I mentioned books and music as starting points, he shot that down as impractical.  How depressing!
