A lot of us spend most of our days having to live by a specific and annoying set of rules. Depending on your job, you may have to dress a certain way and follow enough protocols and behavior modes to fill a phone book.
So when we get the chance to drop all that and be wild, it's hard to think of a greater feeling. There are no fake smiles and no uniforms. Just you and whoever you want with you, acting however you want to act.
And if you wanna act like one of these people, I don't blame you.
