I definitely agree both about Miss Amelia's queerness (funny, to me she read less as specifically lesbian—I mean, there's not really any suggestion of an actual relationship with another woman—and more as very easy to understand as queer in the context of her general oddness and the general sense of her as someone living sideways-on to social expectations and 'normality', as it were) and about the nature of her love for Cousin Lymon. I think one of my favourite things about the story is how McCullers makes those elements fit so naturally and logically into the lyrical fairytale-ish shape and style of the thing (it's called 'ballad' for a reason, I suppose).

That all sounds fun!... I shall have to try some more examples :D
