From here:

"Most of the time nobody knows where they are, or cares, and their togetherness is all that keeps them both from being lost. They go to karaoke bars and drug parties, pachinko parlors and, again and again, the hotel bar. They wander Tokyo, an alien metropolis to which they lack the key. They don't talk in long, literate sentences, but in the weary understatements of those who don't have the answers."

I need to see Lost In Translation again.
