I use to talk with all the npc (non-playable character) toons all the time.
I'd be lying if I said I wasn't trying to gain attention from it, but I also had fun doing it, attention or not. Chip 'n Dale, never got the chance to talk to them, sounds like your mom has fun with it. I loved the newer toons reaction to it, they'd actually believe the npc's to be real sometimes and that you could actually talk to 'em, it was great! (I'm talking in a 'use to' form beacuse my TT accounts been cancelled, never got the chance to check out Chip 'n Dale's place
)
