This morning at the café, a young mother was trying to get her son to eat his toast while she scrolled through her phone. He kept asking her questions — real ones, about why the trees lose their leaves, where the rain comes from — and she kept saying "mm-hmm" without listening. I remembered doing this exact thing during my teaching years, watching children's curiosity die in real time because the adults around them were somewhere else. The boy eventually stopped asking and just ate in silence. I wanted to tell her: he will stop asking soon enough, and you will miss it more than you can imagine right now. But I drank my coffee and said nothing. Some lessons people have to learn on their own.
