I have heard of a man lost in the woods and dying of famine and exhaustion at the foot of a tree, whose loneliness was relieved by the grotesque visions with which, owing to bodily weakness, his diseased imagination surrounded him, and which he believed to be real. So also, owing to bodily and mental health and strength, we may be continually cheered by a like but more normal and natural society, and come to know that we are never alone.
Henry David ThoreauFriendship is the unspeakable joy and blessing that result to two or more individuals who from constitution sympathize. Such natures are liable to no mistakes, but will know each other through thick and thin. Between two by nature alike and fitted to sympathize, there is no veil, and there can be no obstacle. Who are the estranged? Two friends explaining.
Henry David Thoreau
