Nothing feels worse than being alone when surrounded by thousands of people. You can watch everyone around you with their friends, significant others, pets, whatever. Watch them smile and laugh. And you know that that’s not you. You know that you’re not going to the beach with those people over there, or going into that bar there; you’re going home. Alone. You’ll probably clean. Or organize your DVDs. Or do laundry. Something to pass the time.
