Boredom finally turned into creativity

Mike and I were working on a major project yesterday, and we told the kids they had to find something to do that didn't involve screens of any kind.  After lots of grumbling, whining, complaining, pestering, and general lolling around, we finally found them doing this:

They made a mailbox for each member of the family and then wrote notes to put in them.  We've been adding little things to them like stickers, candy, drawings, etc.
