I actually made quite an effort to throw pot-luck or pizza evenings together but aĺl my "friends" turned out to be fake when my perfect attendance record became sporadic. Fake friends =fake social life.
JWs tend to invite you when you're "of their sort" and drop you as soon as your congregation social/organizational status drops off.
There is an episode of Black Mirror set in a not too distant future world where your whole is dictated by social points you accumulate or lose and it reminded me of JWs.
