I suddenly like you a lot more now.
You know what's a really painful thing, musically-speaking? Having a friend who's a Greatful Dead fan.
My friend Tim loves them for some strange reason. I met him about 5 years ago through an ex girlfriend (Tim's wife and my ex were best friends), and we used to go hang out at their place a few times a week. And inevitably, we'd end hanging out in their converted garage playing darts, cards, or pool. And almost always, Timmy would throw on some God-awful GD record, and if he got really drunk or...something else, he'd start expounding about how awesome they were, and how he'd been to like a dozen of their shows when he was younger, and blah blah blah. None of us had the heart to tell him it sucked (well, his wife did...repeatedly), but my ex and I just acted like good sports and pretended we were somewhat into it.
God, how do they have so many fans? No amount of drugs or alcohol makes that crap good, let alone bearable.
