Under age: Wine? Gross; it's like drinking sand. Who does that?
21 years old, living at home: No bills! Freedom! No wine: BEER ALL THE TIME! WOOHOO!
22 years old, living in an apartment: Can't really afford wine. Go to Olive Garden; take remains of enormous bottle home; drink for a week! Woohoo!
25 years old, living in a house: Must have wine for special occasions. Never drink it because it cost real money. Pretend to understand what constitutes "good" wine; attempt epic wine snobbery.
30 years old, owning a house: I make decent money. BUY ALL THE GOOD WINES AND DRINK THEM! WOOHOO!!
35 years old, with a child: Bills! School fees! Retirement planning! Drinking with friends is a long-forgotten treat. Fuck it: I'll take the box.
