This is brief, and has a point...for us.
Our first experience with alcohol was in the 8th grade, when we were about 12.
Two female friends, and us, spent the weekend together, both nights at a different girls house (but not ours).
The first night, on a sleeper sofa in her parents living room, with the house to ourselves, "J" said there were wine coolers in the fridge and said we should drink some of them.
At that age, with a strict Christian up-bring, and the seeds of a desire to rebel, parents just having split, Dad raising two sons and a daughter all on his own, and a few of us having the responsibility of taking care of two young brothers part-time...we jumped at the chance. Growing up there was never alcohol, that we knew about, in the house.
Sneaking to the fridge "J" took a few bottles out and we shared each wine cooler together; and then panicked about where we would hide the empty bottles, and how we explain their disappearances from the fridge. Whipping them out into the wooded area near her house we decided she would blame her older sister (who ended up getting in trouble).
The next night we went to "M's" house, her parents were out, and so we made drinks of Kool-aid mixed with whatever hard liquor was in the house (it was probably rum or vodka). A few drinks later and we were sliding down the stairs of her bi-level house, on our bellies, over and over, giggling.
After that it was a few years before we ever drank again, the only exception being a couple of times when The Mother gave us alcohol when we would go spend time with her and her girlfriend (Unpleasant Woman) in the "big city"; and a few [significant] times scattered throughout high school. We were never popular, or "normal party girls", so never went to high school parties. We had limited access to alcohol. We never got out much, and anyway, pot was much easier to acquire and smoke during school hours with cigarettes near the school.
