Today I saw a toddler walk face-first into a glass window. His mother crouched down to pick him up, attempting to comfort the child while at the same time not letting him see that she was laughing.
"Is he okay?" I asked.
"This has really never happened before," she responded.
His older brother, who was not too far advanced from toddlerhood himself, looked me straight in the eye and flashed me a knowing smile.
