DH's cousin past away 8-9 years ago (or so, I am not sure how long ago). They are having graveside services for him tonight (the anniversary of his death) and dinner at his parents house. I told MIL that I did not feel comfortable attending (didn't know him), much less keeping my 1 & 3 yo's quiet and calm during this w/o DH's help (he will be at work).
DH and my SIL understand and agree. MIL was just quiet when I told her we wouldn't be there. She did the same thing to SIL when she said her 3 yo DS who just had his tonsils out Tuesday will not attend.
Re: I *think* I made MIL mad...
I guess I don?t understand why your MIL would be so upset. Makes no sense to me, and I feel you did the right thing by not going.
