From Wednesday, April 19 1995 at 10:30 a.m. to Sunday, April 23 1995 at 2:30 p.m. in Chicago, Il I did not speak to anyone. On a number of occasions i encountered someone I knew, however, in order to complete the experiment, DI feigned being in a hurry to subvert communication with an acknowledging nod of the head or a wave. The investigation desistd after five dsays when I said "hello" to an unacquainted passerby on the street.
