My 3-year-old son walked up to me a few moments ago and clambered up onto my lap. He placed his chubby hands on either side of my face and gazed into my eyes.
"I wuv oo, Mommy," he said.
As my heart beat pitter-pat, he reared his head backwards and slammed his forehead into my own. As tears welled up in my eyes, he laughed maniacally and pronounced, "Head bonks mean love," and walked away.
