Ahhh, the dick of all dicks (pause). We're not talking about at the airport terminal, when somebody is just dropping somebody off here. We're talking when you walk out of your house or place of business and you see your car boxed in between three cars and a wall. There's absolutely nothing you can do except wait.
Wait for that person to come back, so you can call them an asshole and finally get where you're trying to go. It could be five minutes, it could be an hour. You never know. What we do know, is even though you think you'd feel better by taking a baseball bat to the person's windows, this, in fact, will not help. Don't do that. Just use your anger to finally beat that really hard level of Fruit Ninja or something.
