You are a fantastic MIL and I'm usually the first to admit that and give you props. You have been infinitely supportive of MH and I, albeit you "joke" sometimes to get your point voiced. (E.g.: Us not giving you grandkids right now.)
However, the stunt you just pulled... I'm SERIOUSLY tempted to tell MH to say we can't make it to Mother's Day. You stooped really low.
[She complains whenever we go to a baseball game that she'd love to go sometime. So we asked her if we could take her to the local team on Mother's Day. She turned us down with a flat "I'm not interested." We'd asked 3 weeks ago to beat any plans that had been made and asked her if anything had been planned yet. She informed us nothing, not even the standard of grilling out in the rain at Uncle Jim's, had been discussed yet.
So after just leaving it hanging at "I'm not interested", Greg just got a phone call from MIL's other brother, Uncle Joe. Joe never hosts events because no one will drive out to his mansion in the country and he and his wife really grate on people's nerves. When family functions have been held, we've boycotted saying "We didn't know about it." (Usually, we don't. MIL tells Joe to call us, Joe never does, we don't know about it, and then hear about it after the fact.)]
I particularly dislike that you informed Joe we "could make it". (His message said "So glad to hear you guys can make it.") We didn't state that and never committed to it. FYI: This is the FOURTH YEAR in a row we'll have spent Mother's Day with MH's family. Since you shot us down for the game, we were going to plan on spending it with my mom.
So just an FYI: your arrogant brother Joe sucking up his pride and calling to invite us saved your a$$. We're going... not because it's Mother's Day and we want to honor you. But because we want to "reward" Uncle Joe for being a man and calling to invite us himself.
Happy F-ing Mother's Day,
Your daughter-in-law
P.S. This opinion is shared by MH. Way to piss off your only son.
