Clean vs. Dirty

Shh! I'm writing this at work. Don't tell Boss.

Part of our grounds care duties involves periodic power washing of sidewalks. Usually it is prior to a special event or school opening, etc. Sometimes we get graffiti. Increasingly, students are advertising programs, plays, presentations, etc.

Today, we received a work order which reads, "Clean offensive chalk drawing in front of building."

Hmm. That's a nice change of pace. Usually, the offensive chalk drawings are dirty.
