Thanks to e-mailers who asked about my scarcity around these parts the last few days. In spring, this not so young man’s fancy has turned to thoughts of . . . the “Arab Spring” — such that I am strapped in trying to finish a project that I’ll have more to say about soon. While I may ring in from time to time on the Corner and on Twitter, I’ll be taking a couple of weeks off from column-writing, including on the weekend. Plan to be back in early May. Over and out.
