Yup, Them Musta Been Aliens

Those wonderfully studious aliens left after 3 days. Oh...I sure miss them. I should have known it was too good to last.

What was it that caused them to buckle down those few days? I simply must know. They wouldn't tell me when I asked them. In fact, they both smiled that "we got one over on mom" smile and didn't say a word. What's up with that? I'm starting to suspect they did something they are going to be in big trouble for (once I figure out what they did)and were trying to be super good to lessen the consequences. When I was a kid my mom always knew when I had done something wrong; because, I would pick flowers and take them to her. She liked flowers. I wanted her to be happy when she discovered what I'd done. Yes, schoolwork would be flowers to me; but,...three days of schoolwork? It must be something major!

Nothing is broken or missing. R is in one piece. What could it be?
