At the time my mother smoked cigs and my dad a few cigars (they both quit many years ago). It seems that all us kids had been pestering the folks with some sort of "You smoke, why can't we smoke?" type arguments. Well, it seems they got the bright idea to let us go ahead and smoke if we wanted, under their supervision.
Here's how it worked. They told us to go collect up all the butts we could find around the house and bring them back for a big family smoke-in. What fun this was and we all came back with a big stash.
So, there we were, feeling oh so smart as our parents proceeded to fire-up our smokes. And they even encourged us to smoke as much as we wanted! But the fun didn't last long.
Soon we all got very tired of coughing, and a stange light-headedness set in. Then a little nausea as my parents asked if we'd like some more.
In the end I think it was a long time before any of us ever smoked anything again. I personally never took up smoking, but must admit to puffing on a few in high school, but never found any enjoyment in it.
I think back on this as a brilliant move by my parents. Stupid adults, we couldn't figure out what they wanted to smoke for, it was awful. However, I do wonder what would happen to parents today if they tried this stunt on their kids. Probably some sort of awful public outrage...
