When Tim died of AIDS 10 years ago, he was cremated. Half of his ashes went to his sister in Maine, who planted an oak tree in the Wiccan tradition. We left the other half for his boyfriend, and that, we thought, was the last of it — until October. We got a registered letter from the funeral parlor telling us that Tim’s ashes had been abandoned for a decade and that if we did not pick them up, his remains would be disposed of. So I drove to Duggan’s and brought the second half of Tim home.
