When I was a wee tyke, I once watched my father make himself a drink that heavily featured tequila. When I asked if I could have some, dear old dad decided it was the perfect time to teach me a lesson abut alcohol, and let me take a big swig of the stuff. I'm sure you can imagine how that went!
While I swore to never drink again (I'll admit, I've relaxed my feelings on tequila since then), it certainly taught me a lesson that many kids learn in similar ways — even, apparently, on movie sets! Peter Billingsley from A Christmas Story just opened up about a similar lesson he learned about tobacco on the set of the film.
