Vanpool of another flavor

Another friend of mine rides in a vanpool to Everett everyday, about 30 miles from Seattle for all you out-of-staters. From my conversations with her, it seems like she *likes* the people in her van. It's left me wondering whether 1) I'm terribly judgemental; 2) the people going to Everett are less grating than those going to Olympia; or 3) I'm just a keen observer of the idiosyncrasies and oddities of those around me. Since I like number three the best that's the one I'm going with, although I have a sneaking sensation that number one might have something to do with it as well.
