I think this very much depends on the circumstances. Few working-age men walk in my neighborhood, and some people seem a little uneasy seeing me walking. They don't know what to make of me.

On the other hand, if I walk a dog it is clear what I'm doing, and people are quick to share a smile. It seems like many people are uncomfortable unless your activity fits into a pattern they're familiar and comfortable with.
