Fyodor Dostoyevsky - Do you know I don't know how one can walk...

Do you know I don't know how one can walk by a tree and not be happy at the sight of it? How can one talk to a man and not be happy in loving him! Oh, it's only that I'm not able to express it.. And what beautiful things there are at every step, that even the most hopeless man must feel to be beautiful! Look at a child! Look at God's sunrise! Look at the grass, how it grows! Look at the eyes that gaze at you and love you!..
