My friend and I were running the other day, in a residential area. It was really cold and snowy, so a couple standing in their garage applauded and kept yelling "good for you!". It was a great feeling...
On the other hand, that same friend experienced two guys driving past her yelling "heffer!"... now, that is not very nice.
I don't know what I would do if someone actually insulted me while I was out trying to be active, healthy, and fit.
