A very happy belated birthday to my sister Gillian, who turned 27 yesterday. (We celebrated on Monday, but, as y’all might know, I haven’t posted here since then.) Update: Also, a very happy Yuri’s Night to you and yours — tonight is the 45th anniversary of cosmonaut Yuri Gagarin’s first-ever trip into space, as well as the 25th anniversary of the first space shuttle mission. (By way of Blivet.)
