You just want to unwind with your favorite beer. You probably have some favorites, whether they're cheap or fancy IPAs.
You bring a 12-pack to share when the invitation states “BYOB.” Could you drink wine? Sure. You like what you like and stick to familiar classics. Enjoy a nice night with a bowl of pretzels.
Beer is simple. Quite comfortable. What you know. Cocktail menus are not worth the stress. With so many ingredients, you can't be sure you'll like it. Then what? Complain?
Not your style. You prefer the classics: a cool drink and salty snacks. Thus, you can focus on other things like eyeing your crush from across the party.
You won't drink solely beer. You pack your fridge with hard ciders and White Claws for parties. You drink whatever's available, but you have a preference.
An easygoing Capricorn likes beer, especially with pretzels, a BBQ, or a game. Being a bro is liberating, and a cold beer helps get you there.
