Consumption of alcohol impairs motor reflexes and judgement, everyone of atleast their teen years should be aware of this. So if you choose to drink, you're choosing to impair yourself, and are therefor responsible for the consequences you may reap (be it saying hello again to lunch, that giant cucumber in the bathroom [hellooooo tequila!], or the death of another vias-a-vie drunk driving). Never an acceptable excuse, only a reason..
