Well ... I did it! There were about a dozen people there.
Thanks for all the encouraging words -- and TIPS! I would not have thought of using the excuse to go to the bathroom to get away from sensory overload.
I managed to put my foot in my mouth in the first 10 minutes by insulting the type of project someone was working on without first checking to see if anyone was working on it.

But I think I recovered nicely by telling her later in the evening when she got farther on it that hers looked so perfect, I didn't realize it could look so nice, and that it looked nothing like when I tried that type of project. And maybe someday she could give me some pointers. Whew.
I made a couple of jokes that people laughed at, and one woman thanked me for coming.
Only at one point did I get overloaded because two groups of people were talking, and I couldn't discern a voice to follow any one person, so that's when I went to get some water. When I came back, it wasn't a problem.
So I think I will try going back (maybe

). Fortunately it's not next week so I have some time to recover.
Alright. I am very proud of you. Cheers.
