Sibling interaction is something I always find interesting so here are two unrelated sibling tidbits I came across today. The first is a story from the NY Times called "When Sporting Siblings Excel" about tennis stars Dinara Safina and Marat Safin. The second is a video of Rufus Wainwright playing "Hallelujah" at the Glastonbury Festival in 2007. He has his sister Martha come out and sing with him and it is cool to see how much they both enjoy it. I love when he starts her over again and she really gets into it. There's a little lag between the video and the audio but don't let it distract ya.
