It went really well, thanks for asking.
Dh's mom seems to have discovered the wisdom of taking hormones (which I have maintained that she needed for the past decade). Say what you will about those little faux woman-stuff pills, but here's my testimony:
Dmil had only been on the things for six days when she arrived on our doorstep. She was a bit catty, but still a far more tame version of herself than I have come to expect in recent history. Her nasty comments, intolerable hot flashes that cause her to rage at innocent bystanders and generally foul mood were in shorter supply than I can recall since dh and I tied the knot. Still, there were more than a few snide side comments, mostly pointed in my direction, and nearly all having to do with the fact that I ordered our turkey dinner from a grocery store.
By day eight on the medication, she was almost mellow. No joke, guys. She averaged one nasty comment a day from then on, and was so darn amiable that dh and I let her take our kids to the movies without us. We were that certain that she wouldn't pull a "Grandma Dearest" on them. She even ate a meal at a restaurant without sending any portion of her meal back. You really can't grasp how unlike her that is.
This was an earth-shattering difference. Prayer and hormones. A winning combination!
