The portal actually drops you off outside a shelter sometime in the evening, since during the day the kids are preferably in classes, unless they're way too young for that. A smiling shelter employee meets you all and guides you inside, where there are kids, most of them pretty small. She'll pair you off with a kid, and just... spend time with them. Play, do crafts, chat, help with homework. Whatever the kid needs.

Mod your kids, kids.
