My three girlfriends and I went out. It's not a usual happenstance, but when we do, it is awesome. That is not the gist of the story, though. As is required, there was the designated driver, although the rest of us were only a little tipsy. When you get to a certain age, getting drunk is too much like hard work, as you cannot forget how inconveniencing a hangover is, and how you no longer have the option of staying in bed all day in recovery.
Being an adult means there are responsibilities eye-balling you constantly, hangover or not. For us, going out is a way of, for a few hours, ignoring responsibilities, and age. It means talking loudly over the music, dancing while seated, pretending to be shocked about the skimpily dressed younglings, giggling at the men with audacity to try and chat us up, sipping drinks at a speed that does not please the club owners, drinking more water than alcohol, and doing regular one-leg stands, just to make sure we are not overdoing it.
