“I am going to give you a piece of advice... advice I wish I'd been told in guidance class back in high school, in between the don't-do-acid and don't-drink-and-drive films. I wish our counselors had told us, 'When you grow older a dreadful, horrible sensation will come over you. It's called loneliness, and you think you know what it is now, but you don't. Here is the list of the symptoms, and don't worry—loneliness is the most universal sensation on the planet. Just remember one fact—loneliness will pass. You will survive and you will be a better human for it.”
