I think it comes down to human nature. We identify with other people - even strangers. I try to think how I would feel in their place. (I'm probably wrong as much or more often than right.) I don't try to convince them to stay when they don't want to be here. It's a bit like trying to get your parents or your kids interested in the music you like. I do try to convince them they'll be welcome if they choose to hang around.
