My dad would say things to me like "Your mum wanted you aborted" in order to hurt me, but then sit back and say he hadn't done anything wrong by saying that.
Is there a name for this kind of tactic? My manager at work does a similar thing, she will say that the admin staff always say "all the mothers who work here are pisstakers" when she knows I hardly ever ask for any shift swaps etc (the blokes ask for a lot more than I do).
its like they want to see the wounded look cross your face but you can't say anything back to them!
