I'm not good at apologizing w/out explanation. I make myself do it. I just messaged my MIL to tell her I was sorry that we upset her last night, b/c I AM sorry I upset her.
I'm not sorry she got upset be cause I slapped her upside the head with the truth. I left that part off, b/c it doesn't need to be said and will just cause more issues.
It's official that I can only stand about 3 hours with my ILs now. And that's mostly my fault. I'm finding as I get older that I don't have patience for things I used to let slide. I can only imagine how much worse I'm going to get in my 40s.
