I find it amazing how many times there are when I'm driving myself to work tuned to NPR and a story comes on that just makes me think, "thank goodness for NPR!" Gosh there is a lot of stuff that I didn't learn (In the interest of full disclosure, my teachers probably tried valiantly to present this stuff to me, but in all likelihood wasn't paying attention at the time …). This story onThe Shia-Sunni Split falls into that category–really worth a listen!
