Why do grandparents and grandchildren get along so well? The mother.

The middle generation pays the price

There's something darkly funny about this observation because it's true. Grandparents and grandchildren often share a natural ease with each other that skips right over the middle generation—and the reason points to something real about how families work. The parent is usually the one enforcing bedtimes, eating vegetables, doing homework. The grandparent gets to be the fun conspirator, the one who slips you extra cookies and doesn't care if you stay up late watching movies.

But there's a deeper pattern here too. Parents are caught in the exhausting middle, trying to raise humans while also managing their own lives, bills, and disappointments. Grandparents have already done that work. They've made their mistakes, raised their kids, and arrived at a place where they can actually enjoy children without the constant weight of responsibility. They're not trying to shape you into anything. They just want to know you.

What Colbert captures with that one-liner is how the structure of family roles creates distance between people who actually love each other. The parent can't relax because they're the one who has to care. The grandparent is free to love without conditions. It's less about the mother being a barrier and more about how parenting itself requires a kind of necessary tension that grandparenting doesn't.
