i 'll do the mental telepathy bit for about ten minutes or so as the target climbs out of the subway stop and navigates skyscraper shadows and finally disappears inside a building that usually has a security guard to keep crazy people like me out.22 so then i just go to the nearest park , sit with the pigeons , and stare at clouds until my workday is over and it 's time to ride home with all the other weary workaday toms and jennys , who look even more miserable on the p.m. return trip .
