I suddenly realized that there is a whole other world out there (the "beer world") of which I know absolutely nothing. I thought My former sense of culture for having tasting a half dozen varieties of cream soda seemed so tiny in comparison.
I am still recovering from the existential crisis that this caused me.
If you ever end up in a similar situation with a bunch of wine buffs it will be even worse. They take things to a whole other level. If beer drinkers gave you an existential crisis wine knowers will cause your head to implode.
Although you could just point out that it is only rotten grape juice they are getting excited about and then watch their heads explode.
