I was riding my bike home after work being a very responsible citizen, abiding by the rules of the rode and even using by hand signals:
I was about to turn LEFT (so I looked much like the above picture....except not a male)
A car that was coming the opposite direction (that I was waiting for before I turned into my neighborhood) put their hand out the window right before they passed me and gave me a HIGH FIVE!
Hilarious. And bizarre.
Luckily I am so coordinated it did not knock me off my bike!
