Isaac Asamov's Dad

My father spent hours with zan, talking to the horse and walking him around a man made pond. I thought he was losing his mind; i began to mourn him from the moment i first saw them. This state of affairs, i thought of it as a decline, went on for eight years. And despite the pain i feel at having lost my dad, i'm now grateful for that time for one thing. Up until my dad's death, my parents lives were what you would call eccentric, but normal.
