Who is Father Snow in the novel, The Girls?

Father Snow is pastor at the city’s Episcopal Church. He is a houseguest at Mommy and Daddy’s house and is the only repeat houseguest, possibly because he is oblivious to the girls’ torments. The girls call him Father Ice behind his back, a nickname they see as ironic since he is anything but ice-like, being very emotional. In this story, Father Snow is deeply depressed about the death of his lover, Donny. He likes to drink martinis, which he mixes for the family during cocktail hour. Father Snow snaps out of his depression at the very end of the story when Mommy drops dead, and he must use his training as a minister to tend to her departing soul.
