I can't make eye contact unless I know exactly how it is going to be interpretted and have practiced for that situation.
I.e. at work it is always the same sort of stuff.
Outside of that very limited subset of situations I either can't make eye contact, burst out laughing, or (apparently) get an expression that makes me look like I want the other person to drop dead and rot away into a pile of slime.
Yeah, I come accross as totally insane sometimes. Hmmm.
Making eye contact is not at all natural for me. I have to look around or I'll drift off and think about more interesting and important things. I try to do it just for other people so they don't hate me.
