a friend request from someone I don't recognise at all, but who has messaged me saying that she talks about me all the time
and seems to know an awful lot about me. I know that she may have changed her surname (got married) but I can only think of two people I have ever known with the same first name, and I know both of their surnames. We have several mutual friends, most of whom go way back but I have very little contact with them, now just the occasional post. Is this normal, or quite weird?
