If I wear a shirt with any sort of pattern or detail on it (you know, anything other than a t-shirt), Tommy will spend quite a lot of time – even hours over the course of a day – tracing those details with his fingertip. Which is what he was doing as he sat beside me at dinner last night, tracing the curves of the print on my shirt – along my side. “Will you please stop?” I asked. “You’re tickling me.”
He looked up at me earnestly. “I don’t know why this would tickle,” he said. “I’m just moving my finger on you.”
“Well,” I grinned, “let’s see what happens if I move my finger on you!”
Guess what? It does tickle.
