Do you following sound as if they could fit?
- Treated admittedly quite badly by a person; proceeded to spend months ringing them and 'harrassing' them, doing things like arranging to view items they have for sale and then not showing up, to 'punish' them. Stops when threatened with police involvement.
- lies ALL the time. Lots and lots of lies, many harmless but baffling like saying birthday is in February not September.
- steals. Minor items but also items from friends.
- has been cruel to animals, has a nasty and vicious temper.
I might add others as I think about them.
