We stopped into a tapas bar, had some great food and a bottle of good French wine. Except once the bill came, we noticed they'd only charged us for a glass, and we may have forgotten to bring it to their attention. Oops.
Instead of appreciating our good fortune and heading home as planned, we applied what I like to call "alcohologic" to the situation, and decided that we clearly had to go celebrate our good fortune by spending the money we'd saved on more drinks at another bar. It made perfect sense at the time.
It's quite similar to the reasoning behind pretty much every night out, where I say I'm going to call it a night and someone negotiates with me, saying that they're going to a bar between our current location and my apartment, therefore I should come along for one more. Forget the fact that a bar being "on the way home" has nothing to do with actually being at home, in bed, and not consuming more alcohol. It's all the rationalizing I need to extend my evening.
So what I'm trying to say is, alcohologic is a beautiful thing, even if it is an ugly word.
