Here are a couple small, light-hearted ideas I encountered recently.
through their website yesterday and found this:
Tardy slips are often available for those who are running late. They may not get you out of trouble, but they'll probably lighten the mood. At least you wont be trying to explain yourself on an empty stomach.
lights that said something like "the bike fairy was here" and "may is bike month" and she left them on the bikes at an elementary school.
What about y'all? I'm sure y'all have thought up/encountered so much sweetness.
