Mostly they ignore me, I become invisible.

One day though when I was looking pretty depressed I did get some awful woman start yelling at me because her dog stole my dog's ball. I tried to be reasonable, even though I was shaking and crying, but she just kept on and on at me, saying that it was a first world problem and that I shouldn't have let it happen.

On the other hand, last week someone asked if I was unwell because I was shaky and weepy in the supermarket. So I think it can work both ways, but kindness is much, much rarer than meaness.
