This, unfortunately, is EXACTLY what high pressure religions/cults/MLMs use to their advantage.
I was a mormon missionary and one of the things we were taught to look out for is things to humanize ourselves. Literally "If you see toys in the yard, ask them about their kids. Are they washing a car? Ask if you can help. Was there a death in the family? Talk to them about mormon heaven." etc.
The key, here, was all about conversion. You find an opening and then try and wedge yourself in (with the ultimate goal of getting a new convert, because you are "saving" them).
Other cults are certainly worse (NEVER go to a "private" meeting!), but it's something to realize. Cults are successful because they try and use genuine humanizing effects to bring in new members.
