I'm an indoors person. I'm not afraid of the outdoors and I penetrate it easily and cheerfully. However, I must admit I like Central Park better than the wilderness, and I like the canyons of Manhattan better than Central Park, and I like the interior of my apartment better than the canyons of Manhattan, and I like my two rooms better with the shades down at all times than with the shades up.
