Is That A Tear?

Clem and I were biking home from school yesterday under a clear blue sky. Clem is rightfully proud of her newly acquired biking prowess. Clem: "I think I just felt a drop of rain on my eye."

Me: (looking up at cloudless sky) "I don't think it could be rain. Maybe it was sweat. You're pedaling super fast."

Clem: "No. It's not sweat."

Me: "Hmmmmm."

Clem: "It must have been a tear of joy."
