“Do anything three times if possible,” goes my motto as a forty-something. Publish three books or articles on different topics but a common theme. Or, dance to three different songs but the same genre from the same period. Or, write three blog posts about the same subject matter in a row. Three books and articles I haven’t achieved. But I’ve done the dancing bit and now I am doing the third thing. My last two blog posts are about Vietnamese Catholic refugees in the U.S. during the 1970s and the 1980s, and this post rounds up the miniseries.
