5 at a restaurant for lunch that would qualify as looking them in the eyes, but many other walked past, only 1 interacted with at the post office but 7 other people I started at their backs when I was in line, and 1 young man at Dunkin Donuts drive through for my coffee. Oh- and a Skype call for work with 3 people, I saw them for sure! And my neighbors (2) were outside at the same time as me today- but I didn't really talk to them. Maybe more info than you wanted!
How many people can you see from where you are right now?
