Again guys, what's wrong with a little wine? She's just experimenting, maybe it'll develop into something worse, but in most cases it'll just prepare her for real drinking later in her life. It's good to have an idea of your tolerance and how to handle alcohol before you turn 18 and are thrown into the world of booze.
In life, sometimes there are proper ways to do things as well as improper ways. If she wanted to try out wine that badly, the proper way to go about it is to ask for it, in a small, reasonable serving; stealing it would be the improper way.
are you justifying being a snitch? snitches in any shape or form are the lowest form of scum and are at the bottom of my trust worthy list.
There are snitches, people who tattle on others for no reason other than to see them suffer, and then there are people who "tattle" because they see something being done that could end up having adverse effects and is just wrong and needs to stop. You know what happens when people look the other way like this? Often those little problems turn into much larger ones (such as, EHEM, stealing).
