It’s certainly true that JWs imagine other people think about them a lot more than they do, and this phenomenon is probably true of humans in general. On these lines I enjoy and try to remember the quote I heard one time: you’ll stop worrying so much what other people think about you when you realise how seldom they think about you.
It’s a great story above from the Catholic priest and underlines the fact that JWs talk a lot more about the Catholic Church than the reverse. This was particularly true in the 1960s when the literature was full of caricatures and attacks on the Catholic Church, the thick red book Babylon the Great Has Fallen! presumably written by Fred Franz being a prime example. At the same time the priest had apparently thought enough about JWs in order to make the judgment that they weren’t worth engaging and to come up with a witty response on the spot. If this happened in the 1960s it’s perhaps worth remembering there were ten times fewer JWs back then and that the Catholic Church has since shrunk in the west. Nevertheless a busy priest indeed probably still has little time or inclination to think about or engage JWs.
JWs are both small enough and numerous enough that it’s not surprising to meet strangers who are either familiar with JWs or who don’t know anything about them, although I don’t remember anyone saying they had never heard of JWs at all, which is commonly the case if I mention the Christadelphians, for example.
