I've seen all sorts on here about mother in laws, whether to add them on Facebook when relationship is new, how they call to see where their precious son is if the relationship has broken down, how they expect to come visit for a week at a moments notice, favour certain GC, show distain if a GC is a certain sex, turn up unexpectedly on your holiday etc etc etc
I realise this is the extreme of MiL relationships but what does the ideal mother in law look like for you?
