Even better, find some friends to watch the game with away from home.
"Sorry, can't make dinner on Saturday. A bunch of us are getting together to watch the game and grill some brats."
Now that sounds perfect!
So, let me ask ya'll this - I got a phone call from my step FIL asking for my W's phone number so they could call and wish her happy bday, which I found very odd because I know they have her number. At any rate, we talked for a little bit and I suspect the real reason for the call came out when he mentioned (more like indirectly asked) that my MIL wasn't all that happy with my actions. Seems that my "snooping" when gathering intel about the EA was told to her family, but she conveniently forgot to mention the reason why I did it. So, to all of her family with whom I really do (or did) have a great relationship, now think I snoop in all her stuff and did all of these other things.... I kept it very civil because I like him, so I just said that there is a whole lot more to the story that isn't being told and left it at that. Was that an appropriate response?
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
