Shabbat Chanuka I encountered a former classmate (high school). I came over. Said hi. Confirmed that she was who I think she was. She said she can't recall my name. I said it. She asked me if we went to seminary together...I, quite unnecessarily said, "high school".
My former classmate had a few kids around her...And for the rest of shabbat I had a recurrent and disturbing thought that maybe my pregnancy/childbearing-related memory loss is not as temporary as I hoped.
