When you're up in the mountains around the camp fire and the person you have a crush on is over grinding on someone else's special place. Instead of saying "screw it" and moving on, you sit alone on a log staring into the fire, reflecting on everything in your life that sucks, whether it's relevant or not. Eventually someone will come over and ask you if you are OK, and give you some random advice that you will really appreciate and remember forever.
"Hey man, saw you over here firedreaming. I just wanted to say I know what's bothering you, and it's not worth it. This is the best fucking time of your life, start enjoying it."
