Needs:
Ok, now. Here we go. You set the chairs next to each other. They represent the bench at the bus stop. One person starts out at the bus stop. (Waiting for the bus. duh.) Then, person number 2 comes along and sits down, and acts as something to try to make the other person leave. Then once person 1 finds a somewhat legitimate excuse to leave, person 3 comes and tries to get rid of person 2 just like 2 did to 1.
