One thing I miss working in my old job (and I knew I would miss it) is the surrounding area itself. There's a lot of stuff within a few blocks: banks, restaurants, barber shops, bars. There isn't as much stuff in my new area. Several shops, and a few restaurants, but no banks or barbershops. No bars, either. Another thing is the surrounding neighborhood. The new office is close to a residential neighborhood, like the old place is. The neighborhood here is nice, with pleasant-looking houses. But the homes in San Francisco have more character. They come in a variety of styles, different from the almost cookie-cutter styles I see in the new area. A lot less trees and parks as well. One of the places was a water fountain where I could sit and relax for a bit. I called it my happy spot. I miss that one most of all.
Edit: I found a video of the area I'm talking about.
My happy spot is shown from 1:24 to 1:29. The last few seconds of the clip show the street where I used to work.
