I would think it could be stirring up a hornets's nest. As Teetime said, coffee, cake and ground rules should be enough. I think issues should be left alone unless they are enormous!
We've had daughters bounce back on an alarmingly regular basis - it hasn't been easy lots of the time but a sense of humour and lots of love go a long way to easing any problems. Also, for you, ranting on GN would be good.
Good luck!
I would like to meet here someone from eastern Europe
