Meetup RSVP don't match who show up.

Most meetup I been too have been a social disaster to make new friendships. I join since I am a major introvert and the people that suppose to RSVP are suppose to be shy.

When I actually attended most events completely different people show up that don't even match the list making me the outcast. I end up leaving. Some groups I end up getting even booted out of.

This is in NYC which surprised me.
