You've got problems. I've got a beer getting warm. Let's make this quick.
The Sin Bin is an advice column for people who don't deserve it. You write in with whatever sad, tangled mess you've made of your life (or your neighbor's), and I'll tell you what you already know, but you're too soft to admit to yourself. Think of it as getting cross-checked into the boards by someone who cares about you. Or doesn't. Look at it this way: you're already face-down on the ice.
Note for the n00bs: Yes, this is rife with hockey terminology and analogies. The penalty box is the sin bin. I almost called it Two Minutes for Whining instead. That could have made it sound like whining was okay as long as it lasted two minutes, so here we are.
