That said - if someone thinks they might be autistic, gets close, and later finds out they are not autistic - no fowl. If you came off autistic enough to get that close, and were seeking the company of whom you thought were similar neurotype, you're an honorary member and welcome to remain that close to me.
If you don't stand out to me as NT, then you haven't been doing the hurtful and exhausting shit that drove me to keep them back a bit.
