It's like that one time, when I got drunk

Just saw Eternal Sunshine of the Spotless Mind. Sometimes I wonder if Charlie Kaufman has been hanging out inside my head or if he's just lived a life remarkably similar to mine and writes about it now. Then again, I take it from his popularity that a lot (if not most) people greatly identify with his sad-sack main characters.

So which is it? Either everyone's been through this shit and we're not as special as we all think, or it's a case of "Malcovich! Malcovich Malcovich Malcovich!"
