What strangers see
Handwriting with a red underline. Reads like a comeback, because it is one.
What you know
The answer to Try to behave. One person sets the rule, the other dares them to enforce it. The push-and-pull is the point.

It's written as a reply on purpose. Stand next to someone wearing Try to behave. and you've got the whole exchange.
