Standing in line at the checkout when 13, in the middle of a very rapid conversation with her sister, randomly throws me a, "whatcha gonno do, bro?" look.
I responded with a, "come at me, man."
And the conversation continued apace and unpaused.

They're enforcing the short/hat/net hair rules at work so I tried a baseball cap.
Coworker whom I affectionately call, "F*cker" (for the record, I'm "Sh*thead") , startled when she saw me and asked what the f was on my head.
"I'm not really a hat guy." I responded, sheepishly.
"No you are NOT."

Working by myself on the second floor tonight. The printer and washrooms are at the other end of the building.
Damn straight I am launching myself up and down the hallway on a wheelie office chair.
I will be 52 in February.
