On his 100th birthday, May 9, 2006, my siblings & I met in Washington, D.C., for the day. Today, his 118th birthday, one sister & I spent the morning laughing together. We discovered we are both obsessed with the 1950s-60s panel show What's My Line? & like the same panelist, remember the same episodes. That funny way of being in tune with someone. Well, especially someone who's your 10-years-younger twin.
