Unique sibset seen on the news

there was a story just now on the news about a pair of sisters who’s conversation inspired a movie:

[name]Twyla[/name] and [name]Dot[/name]

I have always had a soft spot for [name]Twyla[/name] and never thought of [name]Dot[/name] as a name…I’m not sure if it was a nickname or not, maybe for [name]Dorothy[/name]. Anyway, I am actually charmed by the names!
