I mostly look at the ground/sidewalk. If there are any plants or flowers around I notice and remember them in particular. I usually notice things about strangers that other people don't notice (fashion items, birthmarks, etc), probably because I am unconsciously avoiding looking at their faces. The same goes for unfamiliar rooms, I can remember the specifics of furniture placement and decor that other people seem to not notice, once again, probably because I spend conversations glancing around the room instead of at the person I'm talking to. As far as eye contact, sometimes I can do it without too much discomfort, other times not. If more than one person is looking at me, I get really nervous. For instance, three restaurant employees standing at the exit thanking customers, I will bolt by with my head down, trying to smile politely but unable to actually look at anyone.
