somehow, I can imagine that when Spock hears something that he finds really hilarious, inside him there is a boy who is laughing like that but from the outside his amusement is very subtle.. and only some people can see that laughing boy inside him. In my mind, this is one of the first things Nyota understood about him: his subtlety being like his own language to understand.
