When you get married the topics of your conversations change. The things you used to talk about when you were dating are never the same after marriage. You evolve from those midnight romantic talks to discussing the toilet paper brands.
A casual evening in a married life looks something like the one discussed in this tweet where you drink some wine and have a deep discussion over something. And that something is never anything serious like politics or sports. Silly arguments about things like your toothbrush color are pretty common too.
