It's one of those weird things...
About 20 years ago I worked in an engineering firm in Boston. This was a few years after "they" let the nuns loose... out of habit, go make a living on your own. My department got one who was certifiably looney and trained her as a file clerk. I honestly believe she was schitzo. She caused unending problems and was pretty useless at work. Her name? Barbara.
A few weeks ago, we had this visiting nun give a "retreat" in my parish. She taught centering prayer, has written a book on enneagrams and had rather crazy eyes but a melodious, soothing voice. Her name? Barbara.
Since both of the above Barbara's are Sisters of Notre Dame de Namur, I did a search on their website. Lo and behold, all the nuns have e-mail addresses and you can look up names by first name or last name. Honest to God, I typed in "Barbara" and about a dozen of them came up! Just for kicks, I used Mary, Clare and Ann and far fewer (one or two) showed. So our suspicions are confirmed through my careful research and your knack for ferreting out truth and justice. Where do we go with our evidence? ;-)
BTW, I challenge anyone to prove that their diocese has more militant nuns than my diocese. They are legion here. I used to say that the reasons there were hardly any nuns in the Catholic schools was because they are out working and being socially correct --- now I say I am glad they aren't in the schools anymore to corrupt the young. It is so sad.
