What's the difference between a trip and a journey?

Watched Glee. Am totally in love. Notice use of incomplete sentences. Those kids have SO MUCH TALENT. I am IMMENSELY jealous. They were amazing. I laughed a few times, but the show wasn't really about the comedy for me as much as it was about the music. Still, I'll definitely be watching in the fall, although I don't quite see how it will last more than a season. But I remain optimistic.
