sketch girl

I already finished the drawing, but I grant Hiram first rights and show you a sketch. I am very curious, he thinks he is going to arouse serious media attention for his campaign. The campaign is about the obligation to carry ID for everybody over fourteen, which is new in Holland. Hiram wants everybody who is being asked to show ID to exercise their right to ask ID back from the police officer. It's a child's game, "gelijk oversteken", I don't give you this unless you give me that simultaneously. How is that called in English?

Ineke had the answer, in less than ten minutes: "tit for tat". How appropriate indeed, I would never have guessed. Thanks, Ineke.
