Advice and insights about making friends
On any online site, I ask very specific questions, my favorite being about a pet they have,or had as a child. A real person cannot contain themselves, getting the opportunity to go babbling on about their gerbil, or cat, or whatever, and are so happy you asked! Scammers & cold fish just change the subject.
Nearly everybody likes to talk about themselves, or things that matter to them or that they are interested in. I always try to keep that in mind.
