I stopped at the intersection to wait to cross when the man on the bike said, "Let's keep it moving!"
I spun around and shouted, "YOU ARE NOT EVEN SUPPOSED TO BE ON BIKES ON THE SIDEWALK."
The guy on the bike responded in a calm tone, "I wasn't talking to you. I was talking to my wife."
She was the other person on the other bike.
"Oh. Good," I said.
And then I felt bad.
