While walking back from the sandwich shop where I bought a Philadelphia hoagie, I was walking behind (about five feet, maybe 2 seconds) a little old lady. She stopped at the light of a busy intersection. Noticing she didn't press the button on the lightpole for the pedestrian light, I pressed the button.
Oldlady: Do you really think that helps?
Me: sure it does!
Oldlady: This is a long light I've been standing here for 5 minutes!
Time passes about 20 sec.
Me: OK our turn now.
