Counter-graffiti?

That is the view out the fifth-floor men's room window at the Varisco building where I rent an office. The picture does not show it well, but there is a scar of graffiti clearly visible in the middle distance. See here?
That little f'you is near about three stories up in an alleyway. I doubt people on the ground would notice it if they walked down the alley. In addition to making a poor location choice, this "artist" picked just about the lamest, most generic phrase in the vandalism handbook. Amateurs!

It takes a good deal of restraint to keep myself from climbing up on the opposite roof of the Dollar General, spray can in hand, to vandalize my own pointedly witty retort. Here is my cathartic e-tort. Fuck you, too!
