Quote #5
Tuzenbach: You're twenty years old, I'm not thirty yet. Think how much time we've got ahead of us, days and days, all of them full of my love for you. (1.183)
Tuzenbach is characteristically optimistic in his view of time. To him, time is something to be valued and enjoyed, not rued for passing too quickly. As far as this play goes, he's pretty much alone in this optimistic view.
