@izzythepush,
I sometimes bump into things or trip because of my peripheral vision, but for that reason I'm very careful so it doesn't happen very often. I was almost crashed into by a woman on her mobile in the grocery store... idiot, walking fast, talking loud, no attention. Some larger or busier stores scare me since some people dart around thoughtlessly (that's mostly at walmart, but not only). On the other hand, many who catch themselves doing that are apologetic, whatever the store.
