Harassment started for me at a really young age. Around nine, perhaps. All of the harassers were in their twenties, thirties, forties, or fifties. It was a scary thing to have to be faced with every day as a kid.
My street is residential and I used to go pretty far out of my way to avoid a house where street harassers lived, and hung out in front of, in order to get to the nearest commercial street where businesses are. I had to get to this street multiple times a day for the bus, grocery store, bank, drug store, etc. Now I have an ipod and just crank it up as loud as I can and wince as I go by.
