I was at an intersection. There are red, yellow, and green lights at these traffic control devices. These are standardized. Red means stop. Yellow means caution. Green means go.
In the world of gay plague testing there are no worldwide standards. Green can mean go or stop. Yellow can mean what the fuck are you talking about or don’t practice caution. Red can mean blood or go or lipstick.
Imagine living in that world.
You already are.
