So many experiences can only pick out a few.
In London I was in service with a very strict nigerian sister who was a pioneer like me. She had a very stern manner and one of her calls was a regular not at home. This particular day she was sure the person was home so she bent down and shouted loud with her nigerian accent "I know you are in there, I want to tell you that if you do not listen you will die at armageddon!" I was dying quietly by her side.
Another sister I worked with insisted on leaving magazines in baby prams left outside of the houses or apartments, she got upset when I told her I did not think it was right to do that.
I had a pioneer partner who was single and very prudish, one day I was talking to a lady at the door and my partner suddenly went red and started to cough and look so distracted that it put me off my presentation. When we left she started saying she was unclean now. Apparently there had been a naked guy standing on the top of the stairs behind the lady I was talking to and I had not seen him but my partner had got a full view.
My mother in law was a pioneer and very erratic and at times funny without her realizing it. She pulled a door shut so hard the handle came off. We stood there looking at each other and the handle when the householder came out and looked stunned. We handed it back and walked off.
One time the bell I was pressing got stuck and I was battling furiously to try to pull the button out when the door opened and I nearly fell in.
The worst experience from a yucky point of view was the time I went to a door and a man opened it with a hankie sticking out of his eye. He had no eye and must have been cleaning the socket...I nearly fainted.
Oh I could go on and on...one last one. My husband studied with a very ardent young man who was crazy about the things he was learning. When we took him on service it was fraught with anxiety for what he could find out to say. One day he grabbed a householder who said he did not believe in God and dragged him to the balcony to look at a tree, he was shouting, look at the tree, look at the tree, who made it?! I had to go get my husband to tell him to calm down.
