Hoy por ti, mañana por mí. This expression is about reciprocity and the golden rule. “You scratch my back and I’ll scratch yours” might also resemble it in meaning, but “Hoy por ti, mañana por mí” has a bit more of a positive meaning. It’s like paying the bill at the restaurant and saying to your friend, “Let me get this one. You get the next one.”
