How many people in your life understand your condition?

My husband understands, although it was mildly annoying when my primary doctor said (paraphrased) "oh they're (me and twin) are on the spectrum" and he laughed so hard before "yeah, yeah that tracks and makes sense now" like wow husband! Rude. (I love him and he was right though, everything made sense)

I guess my twin understands but we both have slightly different manifestations and sometimes get feral with each other because of it.
