We'd go to a neighbor's house (single little old ladies were best) and ask to use the bathroom because there was no water at our house. That usually led to us getting to bathe and was always followed up by a big meal with leftovers to go. They'd bring us snacks frequently.
School lunches used to come in 2 prepackaged containers. One for hot food, one for cold. I'm not sure exactly how but the lunch lady learned of our circumstances. Rather than throw them out she'd box up the cold part and drop it off on our porch.
One neighbor kept a very well stocked pantry in her unlocked garage. More than 1 can of peaches or soup found it's way back to our house via my brother. No judgements please, we were kids and we were hungry.
Much of my mother's jewelery and anything else they'd take wound up at the pawn shop. We'd sneak in while she was passed out and take something then hock it. Then we'd head to the grocery for crackers and vienna sausage. Again, don't bother with the judgements.
