"At a certain age children are greatly intrigued by the possibility of locating themselves on a map. It appears strange that one's familiar life should actually have all occurred in an area delineated by a set of quite impersonal (and hitherto unfamiliar) coordinates on the surface of the map. The child's exclamations of "I was there" and "I am here right now" betray the astonishment that the place of last summer's vacation, a place marked in memory by such sharply personal events as the ownership of one's first dog or the secret assembling of a collection of worms, should have specific latitudes and longitudes devised by strangers to one's dog, one's worms, and oneself. This locating of oneself in configurations conceived by strangers is one of the important aspects of what, perhaps euphemistically, is called "growing up". One participates in the real world of grown-ups by having an address. The child who only recently might have mailed a letter addressed "To my Granddaddy" now informs a fellow worm-collector of his exact address – street, town, state and all – and finds his tentative allegiance to the grown-up world view dramatically legitimated by the arrival of the letter."
