Nervous habit?
I am still wondering what Sean Marquette's character Mod was doing with his fingers most of the movie. He would repeatedly shake his hand and cause his fingers to smack together - but I don't understand why he does this. It doesnt seem like this would accomplish anything. I am guessing its a nervous habit, but I still am not getting why that particular motion would provide any relief anxiety or otherwise.
Does anyone do this themselves or know someone who does (and why)?
This is really bugging me.
