as long as it doesn’t spiral out of control into dependency, my normal response to someone demanding to pay me for some kindness i’ve done them is either a request for payment in kind (“you know, those pies you bake sometimes always smell delicious from next door...”, “hey, you’re an IPA guy right?”, etc.) or a request to pass it on and report back what they helped someone else with.
I don’t need to take money from neighbors, but i known how itchy it is to feel like you owe someone a debt, and there’s a barter/trade solution that works nicely here and is somehow fundamentally more human.
