There’s a difference between respectlfully attentive eye contact (flits to other things occasionally, but refocuses), fighting eye contact (straight staring, tense facial expression), flirting eye contact (flits between eyes and lips, soft facial expression), and autistic eye contact (direct and unwavering eye contact that drills into your soul for seemingly no reason).

Most likely, everyone just knows (at least implicitly) that you are autistic.
