I never pondered about this until yesterday when I was on another chat way far from the forest. I was talking with these guys about Chrono Trigger SNES/DS, more so about the three ladies of Chrono Trigger (Ayla, Marle, and that one, Velma I think.) Anyways, here's what I noticed: When you go to Crono's house, his mom never gets upset about him bringing those girls over. I mean, most parents don't really care, but dammit, think about it for a second.
Say you're in a party with Lucca and Ayla. Lucca's the childhood friend of Crono and it could be possible she has a crush on him and Ayla . . .well, here's Ayla
You never notice that Crono's mom never gets upset about Crono bringing those girls over to his house, to his bedroom, to "recover H.P." . . . overnight. She never says anything like asking the girls if they wanna sleep in different bedroom or walking anything of that matter.
All in all, Chrono Trigger teaches people about bad parenting skills and not giving a damn who your son comes home with to spend the night.
