A lot of Autistics have trouble making eye contact. If we do make eye contact its usually very uncomfortable for us. I can and do make eye contact a lot of time, as it was expected of me growing up. I have never really liked making eye contact though, so whenever I wouldn’t look at someone while they were talking or while I was talking I would get yelled at when I was a kid. As it seems NTs think if you aren’t looking at them while in a conversation you must not be listening.
If you know someone is Autistic, please don’t expect them to make eye contact all of the time, or at all if they aren’t comfortable doing so.
