social psych?

While attending my debt management session, I found a piece of paper on the floor printed with this:

(1) Sara, please pass this to WILL HOLZER, who is directly behind you, two rows back (behind Karen).

(2) Will, please pass this across the aisle to KRISTEN GERWECK. She is one row in front of you, on the end of the middle section, just across from Nancy.

(3) KRISTEN, please pass this to TIM JACKSON. Tim is in the row behind you, two seats over, next to Janice.

(4) TIM, please pass this to JEREMY JONES. Jeremy usually sits directly behind you, two rows up.

(5) JEREMY, please bring it to me after class.

Many thanks!
