Really only my immediate family knows about PT and they all think it's a pretty neat place. My hubby has trouble sometimes keeping everyone matched up with their pets but he is getting better. He and my son both belong to a couple of car forums so they have online friends as well, although nothing like the friends I have. :) My daughter has been drawn in and is a PTer too so she understands this place. :)
If I were to tell my co-workers they wouldn't understand and think I was dealing with some internet Kooks. haha! I guess I am an internet Kook. :p
