He stays fairly quiet during dinner but he can't help himself. He still finds things to talk about even if he doesn't expect Lan Wangji to respond to him. He is just too used to talking during meals to just be able to stop. So one sided conversations have become fairly normal. He knows that the other man listens though even if he doesn't always contribute and that is all he cares about.

When he finishes he sets the utensils down and sighs contently. "It tasted good too, Lan Zhan."
