Shopping for groceries at King Kullen.
First, plant your husband in line.
Then try and push your cart ahead of me to get up to your husband at the front of the line.
Then watch me say, "I'm sorry, the back of the line is there."
Then try and push anyway.
Then listen to me say, "you know, some other day, I might actually let you break into the line, but not today. I really have to pee."
