No votes for amn't I. Most for aren't, followed closely by ain't/int (I'm allowing for regional variations here) and one, slightly confusingly, for am I.
The reason I ask is that I only know two people, who don't know each other, who say or write "amn't I?" And both of them are gay men. I do not suggest anything from this, I'm just mentioning it.
Happy Mothering Sunday to any and all of you who have, or who ever have had, a mother.
It's just four years since my mother died. In her sleep, in her own bed, with me and my daughter asleep in the next room. Not at all a bad way to go and I'm not remembering it sadly.
