Tonight I had one of those startling experiences of seeing myself as the world sees me. I didn't like it. I made my bank deposit after work and hurried to the bus stop, running the last thirty yards or so because I saw the bus approaching, didn't want to miss it, and was in a playful, energetic mood. I deposited my fare and smiled at the bus driver. I was surprised when, with warmth in her voice and eyes told me, the driver said to me, "I don't like to see you running you could fall." "But I'm not old enough to worry about that." I protested automatically. She persisted. "It's dark and the sidewalk's not even and a fall can be serious." I thanked her for her concern, which seemed genuine - but I just don't think about myself as someone who shouldn't run to catch a bus - or someone for whom a fall could be serious. Denial? I don't know.
