ASK JUNE: The Deathbed Jezebel and Ze Pronominal Protocol Problem

Dear June,

My mother has cancer and is unlikely to live out the month. She and my dad (who has dementia and is not part of this equation) belong to a devout and strict religious denomination, in which my siblings and I were raised. The last time I saw her she told me, and apparently she has also told everyone else in the family and half the nurses in her personal-care facility, that she will not be able to rest easy in the afterlife unless I promise to give up alcohol and non-marital sex (although she calls it “fornication”). I have no intention of giving up either one. That is not my question. My question is whether I should promise anyway.
