I just wondered how other people feel about this. If I'm going along a fairly quiet street and I pass someone, I tend to smile and make eye contact (and maybe say Good Morning). Now, I don't do this walking down Oxford Street, but I grew up in the suburbs and just seemed something I was brought up to do.
I'm surprised at how many people don't do this. Is this normal? Is this some strange cultural thing that people have forgotten? AIBU to smile and make eye contact?
