You know, I’ve often wondered if Mr. encouragement/have-a-chat has any ulterior motives for his gregarious attitude

I can only think of 2, he’s either a bum boy or religious fanatic.
I’ll just need to keep an eye on him and see what he ends up doing or saying out in the car park.
I guess if he hands me a copy of Watchtower or some similar publication, that would be a good indication of his inclinations in one direction and if he offers to help me get out of my wetty by getting in there with me it would be a good indication of the other direction.
Not really sure what to think if I was bending over getting out of my wetty and he delivered a copy of watchtower up my ginger. That would be confusing.
