My sister started a tradition many years ago(I'd say it is a family tradition but, not only is it not practiced by most of the family it's not known to most of the family)it consists of putting family members that have pissed her off on an imaginary bus and gleefully imagining it driving over a cliff. There have been times when there were no empty seats and other times there was only a driver dozing at the wheel as the bus plummeted to it's fiery fate. I'm pretty sure that, even though I have known about the bus,I too have occupied a seat.
It's kinda a joke now. I know I am close to crossing a line when, during the course of a conversation my sister grows quiet and with a glint in her eye says "Don't make me put you on the bus, Vickie." I chuckle and back the hell up, strange things have been known to happen when my sister gets angry.
Anyway, with the economy and environment being what they are perhaps a sack would work just as well...
