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!
