Estragon: I am happy.
Vladimir: So am I.
Estragon: So am  I.
V.: We are happy.
Estragon: We are happy. (Silence). What do we do now, now 
that we are happy?

You tell me.

MG Happy means together.
Are we together ?
You mean…here?
In general.  Together in general.  (Points to nowhere especial): In this, for example.
Let's go. I have nothing more to do here.
(Adds after a while):  Nor anywhere else, as a matter of fact
 Let's wait here. Maybe somebody comes.
Will he tell us what to do with all this staff here? (Points to a faraway spot in the wilderness)
