That's not what happened in the second, regardless. You said the man "never" laughs, you were simply wrong.Is that how you "laugh"? You go "huh" once while smiling?
It wasn't even difficult to find some examples. While he doesn't laugh nervously and in a cackle like Kamala, he certainly does laugh... Maybe not often enough for you, I guess... but why would that matter to the rest of the world?
