Slap a dude
Angrily or flirtatiously. Your call.
Go to a cozy pub alone in a foreign country with a book
But so no one hits on you be sure to be reading something like How To Marry For A Green Card When You’re A Sociopath.
Order a fancy cocktail at a dive bar
But stick with the classics, like appletinis or Pink Squirrels (3/4oz creme de noyaux, 3/4oz white creme de cacao, and 1.5oz heavy cream). Sit and watch the bartender become increasingly agitated.
Go in your stupid bridesmaid dress
If you have to wear that thing, WEAR that thing. And then, throughout the night, hand people scissors and let them cut pieces off of it. After the wedding, of course. Or before! YOLO!
Have a Before Sunrise moment with someone you’ll never see again
Don’t leave the bar with this person, but connect on, like, a super-deep level. And then see them 10 years later in Paris and decide to get married. And then 10 years and a pair of twins later while on an exotic vacation decide that you were never right for each other in the first place. Jesus, this just got depressing.
Watch the World Cup and day drink
Root for any country for the most opportunities to do this. And learn how to say "cheers" in several different languages so you aren’t sniffed out as an impostor and banned from that country forever!
