I forgot my ring at a friend's place after a midsummer party when I'd done the dishes. I don't wear that ring that oft, but it has a special meaning to me, and I keep thinking about it all the time! He said he'll bring it the next time we see, no worries, but I wish I had gone back the moment I noticed I'd forgotten it...
Getting a label on it has helped me a lot! Also I understand other people better as well. I can easily see who's an Aspie as well
