Multiplicity

Sometimes its a trigger, sometimes its prearranged, sometimes its situational, sometimes it's because the one who was out is tired or stressed, sometimes its because someone has cabin fever and just needs to strech out, sometimes its for no reason at all and someone "falls" out.

I am th usual bus driver tho. At work we have an adult group that circultes through out the day sharing. at home we have a domestic group that circulates, but im the driver of each circulation, and i rely on each group heavily.
