Has anyone ever accused of you being “defensive” when you weren’t?

I asked this question elsewhere else recently but I thought I’d ask here too as I’m curious. 

I got into a bit of an argument with a friend recently due to a misunderstanding between ourselves. We were talking about something personal and then a couple of days later she messaged me to say that I made her feel bad because I apparently got “defensive” as we were talking. 

I was really confused by this because I didn’t think I *was* being defensive (still don’t) but obviously that’s how I came across to her. Anyway, it got me wondering if this was an autistic thing and apparently it is. I read a blog post from an autistic woman saying how our facial expressions and tone of voice can be mismatched with our real feelings, so in a NT orientated world we are often misunderstood based on these things alone. It would explain why so many autistic get accused of being “rude” when they aren’t. 

Has anyone else experienced anything like this?
