On my 70th birthday, I ironed my best blue dress, set the dining table for four, and waited by the window until the candles melted down into little pools of wax.

No one came.

Not David, my oldest, the surgeon in the city. Not Karen, my daughter, who married into a family with a lake house and a boat. Not Tommy, my baby, who once fell asleep in my arms every single night for six years.
