Stephen Leacock Quote
How strange it is, our little procession of life! The child says, "When I am a big boy." But what is that? The big boy says, "When I grow up." And then, grown up, he says, "When I get married." But to be married, what is that after all? The thought changes to "When I'm able to retire." And then, when retirement comes, he looks back over the landscape traversed; a cold wind seems to sweep over it; somehow he has missed it all, and it is gone.
