You can tell from the photo above, taken in a motel room sometime in 1970s, that sharing did not come easily to me as a child. While my siblings are perfectly content to sleep three across, horizontally, on a double bed -- my brother already snoring and my sister basking in the breeze of the air conditioner, inches from her face -- I'm shooting daggers at the camera. It was probably my dad behind the lens, proudly documenting my mom's genius for fitting ten pounds of flour in a five pound sack.
