@APBBlue I’ve discovered I get worked up a lot and quickly about a sudden, large change in plans, particularly when it involves now being with people people when I was ready for a stretch of not being with people. (There’s a tiny chance my introversion has deepened as I’ve gotten older).
On the upside, it almost always works out just fine and I have a genuinely good time. But that first impact when I hear about the change is big.
All of which is to say, hope it goes well for you.
