Wow, you just brought some memories. So much to think about in your post!
Since I was born in, I grew up going house to house preaching. I gave my first WT and Awake magazines to a person when I was 4. It wasn't a big deal to me. In fact, as the only activity where I could get out of the house, I actually enjoyed it. Also, that was the only way I was able to know the areas where I grew up.
However, as an adolescent and a young adult, many, many times I was paired up with people who the rest of the congregation didn't like. Those were people who were arrogant and pushy with people.
I learned how to handle them. In fact, I remember this one older guy who people hated going preaching with because he was very talkative and had a mind of his own (you know that in JW land that's a big no-no). At the same time, the people in the group weren't that fond of me either, so they thought that they were going to make me miserable by having me go with that man.
I noticed that the guy had a lot to say about a lot of things, so I let him talk and talk and talk. In fact, I encouraged him to talk more by asking him questions. Turns out he was quite an interesting person with a lot of knowledge about a lot of things. So we had a great time preaching house to house, he did and said whatever he wanted and I had absolutely no problem at all.
When we were done, ready to part ways, in front of everyone he express how delightful he was of going preaching with me and hugged me. Of course, the rest of the group hated me more.
I know well how dreadful it is to deal with everything around house to house preaching. I don't think God is anywhere near those events or people.
