Milk is for babies. When you grow up you have to drink beer.
Milk provides nutrients for babies and it makes them happy. As we grow up, milk isn’t an important part of our diets, we can live without it and it does not make us ‘happy’ as it once did when we were babies.
As we get older, with responsibilities and other life challenges and stress, having a beer once in a while can bring temporary happiness. And, it also helps with socializing, and even finding dates. Cheers to adulthood!
