Funny you should mention this, dear NikL (peace to you!). My dear BIL came over last week to look at our toilet which needed the brass coupling replaced. He... wait for it... brought our neice's dog with him. I didn't get why, but what the hey, nice dog, etc. I had to fence my two in, though, because they're not used other dogs being in the house (only's happened once before in their lives)... and went berserk. Ennywho, I spent most of the time chasing the dog (to get it off the beds, sofa, etc.), so he was pretty much alone in the bathroom. He's a REALLY nice guy and I didn't want to, you know, stand over him while he was working, so I stayed away.
When he left, though, he said something that helped me understand the dog. He said, "You know, I was worried about what your neighbors might think." I thought/said, "Huh? Whad'ya mean?" And he said, "Well, you know, that whole Jehovah's Witness thing, you're home alone, a man comes over..." Crimey. Never even crossed my mind. He's my BIL, fergawdsake! Then I thought... ahhhh, yes, the dog. Our "chaperone", so to speak - LOLOLOLOL!
Anyway, I said, "Yeah, well, that's always bothered me, that two well-meaning adults can't be alone because they either can't control themselves or are obviously up to something. What always got ME was all of the shenaigans going on at assemblies... people leaving their seats to meet/pass by one another and "touch"/flirt in the hallways... when there were well over 10,000 Witnesses right in plain view! Please... the fact that someone is or isn't "around" isn't gonna stop anyone from "doing" something if they want to do it... or make someone "do" something if they don't!"
Think about it, dear one: how many JWs do you think were thinking about someone other than their spouses... while sitting in the midst of thousands of "chaperones"?
Your concern here is a bit of your previous indoctrination, perhaps coupled with a bit of your own insecurities. Do you trust your wife? If so, then you've got nothing to worry about. You wouldn't expect a woman to leave her house just because the plumber came over, would you? In fact, she'd have to stay, would she not, rather than leave a stranger alone in her house? Same thing with a man needing his house cleaned. It's just business... until it isn't. And if something IS "brewing"... it doesn't matter if she's cleaning his house or not.
Give your WIFE... some credit... and trust... here, even if you don't [think you can] trust the "brother." If something's up and she's on the up and up, she'll tell you... and quit. Nothing to fear, dear one... but fear itself.
Again, peace to you!

P.S. And although you might THINK that this isn't about trust but about what they're not "supposed" to "be doing"... you're either fooling yourself or a bit immature. Because it's business... that's all. And that's what they will tell you when you "report"/try to make an issue the situation. The only result is that your wife WILL feel as it you don't trust her... which can eat away at a marriage like nobody's business (pun intended). Peace!
