I sat in the back row of the Facets Cinematheque for Saturday morning’s program of animated shorts, the first in a monthly series aimed at families with small children. As one of only two childless adults in the room, I thought the smartest choice would be to keep out of sight. In retrospect I should have chosen the second-to-last row; about halfway through the program a one-year-old, taking what appeared to be some of her first steps, set her sights on my aisle seat as the finish line for her wobbly trek from the front of the house. I was in the bathroom when she set out; she was in my chair when I returned, her mother sitting on the floor next to her and giving her a valedictory patting. I didn’t ask for my seat back.
