In last week’s Wednesday Witness column, I described one of several homeless men and women who frequented Yale’s campus when I attended in the 1990s. I worked for the graduate School of Music all four years, and one of my first and primary duties was walking the entire campus, distributing or hanging concert flyers and posters at various buildings, businesses, and kiosks. I made the rounds at least once a week; as a result, I saw the local homeless frequently, and they saw me.

During my first year, one man, in particular, kept his eyes open for my brown leather ballcap and black poster portfolio. He was an older fellow, creased and grimy from years on the street, with lank and thinning gray hair, well-worn workman’s clothing, and the unmistakable aroma of body odor and booze. Whenever he saw me, his pale eyes would pull into focus, and his mouth would break into a smile that was equal parts crooked yellow teeth and no teeth at all. He would rise (if seated), reach out to shake my hand, and start the same conversation.
