Personally......I considered that the person was 'inclined' to accept the Truth but that day was not the most fertile for seed sowing.....thus by my being polite and showing up acted as an 'informal witness' and this would add eventual to their accepting the Truth at the proper time and season of their lives before Armageddon started.
That said the congo I am in now has the exact opposite POV..... they reviled and ridiculed everyone who doesn't accept immediately. I remember one of the last book studies I attended with the Nazi PO he commented on a house whose owners never answered the door when we came calling... I thought again , not their time, being polite and unconfrontational..... he on the other hand made fun of them and had everyone laughing at how they would feel when they were about to be destroyed realizing they should have answered the door....
