eye contact

I smile and/or wave!

it depends where I am. If I walk one direction, I would say hi to most of the people, they are older, wealthy, sweet and generally walking their dogs or kids. If I walk the other direction I don't say anything, avoid eye contact and look at the ground. It turns into ghetto, there are gunshots, there is a child rapist at the end of my street and constantly someone digging through the trash at the carwash looking for who knows what. There are loud fights and screaming matches all the time. I avoid that side. Its funny how they are within two blocks of eachother and such extremes.
