“People tell me I’m very odd all the time. I got tested once to see if I had Asperger’s disease. Dad said it’s for people who are smarter than everybody else but can’t run straight. The tests weren’t definitive. Are you sure you didn’t know him? Thomas Schell? He was in the building - 9/11. I’m trying to find a lock for this key that was in the envelope that once belonged to my father.”
