Can I ask you something is definitely something that comes out of Adam's mouth multiple times a day. Crowley is more than used to it by now - for the most part, it doesn't bother him (unless he's trying to do something in particular, like make out with Aziraphale).

After all, what sort of rebel-questioning-God would he be if he tried to quell the boy's inquisitive side?

Right now, he's trimming his rather meager collection of house plants, so it's really no trouble to be interrupted. It's not even an interruption - he doesn't even pause in what he's doing, just shrugs.

"You just did, but go on then."
