give you an example: There was a hoiler than thou, devout couple in my cong who had a son. The son aged about 5 had chicken pox, they took him to the meetings, never missing one so that he would learn that you did not miss a meeting!
The result was several of the infirm and eldery ones contracted either pox or associated illness like shingles. Oh what a loving lesson!
And i lost count of the amount of times i had a JW choughing and spluttering over me as they tried to "encourage" me. What a clean people they are!
