This is bad and you guys are answering after seeing the answer we all know it. By the way chalkboards are blackboards. Blackboards are chalkboards and both are GREEN not black you stupid riddler. And a little something called dust makes so that just because it’s dirty it doesn’t HAVE to be white god you make these riddles stupid and such a stretch they’re just wrong. I came up with this in seconds. I cry but I dont shed tears I jump but don’t fall I eat but I don’t chew what am I.

Sean, you’re getting mad at a riddle that makes sense. There are black blackboards, not just green. LOOK IT UP.
