I'm 52, I drink... sometimes a lot. Camping or not. I am a quiet drunk. Usually sit there with a stupid grin on my face. Daughter #3 is 26 and may have one drink around the fire pit... if any at all. She is loud, just by nature. I think it's because all her life she had to talk louder than her sisters just to get a word in edgewise. When we camp and she visits I am always saying "Lindsay... SHHHHH!" Whether it's playing cards, campfire conversation, or even on the late night walks to the restrooms, I find I am constantly telling her to "BE QUIET!" in a whisper. Point is, don't blame the booze, it's the person. Call a spade a spade.
