I don’t know about that. I’m a nervous laugher too and to me it looked like a grimaced laugh. We’ve all seen him laugh for real, for joy. We know what that looks like.

This one wasn’t that. His eyes were pinched and his face was tense. It’s clear his facial muscles were clenched and the laugh felt forced. Not genuine.

I personally think too many people are making too much of the laugh beforehand.
