Me and MIL do not have good history.... in actual fact I cant stand her... many many justified reasons.... HOWEVER I dont show her I cant stand her (ok I have lost my temper twice with her, again justified) but I popped in my local centre the other day during my lunch and she was there, the cheeky cow blatantly blanked me, suddenly developed a fascination with the ceiling.... should I actually bring it up with her and find out what her problem is or just leave it
