You can enjoy a beer all month long. Beer stains wash out. You don't have to wine and dine beer. Your beer will always wait patiently for you in the car while you play football. When your beer goes flat, you toss it.
Beer is never late.
A beer doesn't get jealous when you grab another beer. Hangovers go away. Beer labels come off without a fight. When you go to a bar, you know you can always pick up a beer. Beer never has a headache.
