My dad invited us (me and my siblings) to try drinking alcohol at home around maybe 15 or 16 so we had some idea of what effect it had on us. He even kind of encouraged us to get s-faced just to see what a hangover was like. The girls demurred but the boys didn't, somewhat to their regret. Anyway, I think he was right to send us out into the world with some idea of what alcohol can do to you, and not so much of it, when you are not used to drinking.
