Occasionally I take photographs of total strangers (but only with their consent)

I was coming back from work today when I passed someone walking down the street playing the accordion in traditional Swiss garb. I asked her if it would be weird if I took a picture (it's not every day you see someone walking down the street playing the accordion). On closer inspection it turned out not to be Swiss garb but just really fashionable clothes. She said she lived in the neighborhood and it just seemed like a nice day to play the accordion.

"Well, thanks for sharing your accordion skills with the world"
"Thanks for appreciating"

I realize I should feel weird about doing things like this, but really I'm just a little kid with a toy camera.
