Small talk could be amusing in its own way, but this sort of gentle teasing, and sharing of some secrets that might not have come out until much later, if at all. For Abbie, too, voices are a thing, and she very much enjoys Dallin's - well. Now that he's actually talking to her.

So Abbie might snicker a bit under her breath, but it's not meant in any sort of a disrespectful way. It would've been ... interesting enough to deal with someone singing around the house, but ... Mormon-themed parodies? "Except ... they were terrible?"
