I started a thread about this and it's been suggested I put this here :o
I have a good friend. Met her when we lived in the same dorm at college and have been close ever since, so coming up on 14 years now.
She is my DD's godmother and I am unofficially her DD's. I say unofficially as her DD has never been baptized as she and DH haven't found a church they like, but she refers to me as her DD's godmother. So we're certainly not strangers!
Last January she asked me if, when she and DH went to Vegas that February for four days, I could watch her DD, who would have been just shy of three and a half at the time. I said yes, I'd love to as I don't get to see her DD much and it would be fun.
She then said she would bring a pack n okay for DD to sleep in. I said "well she'll be a bit big won't she, I can just borrow a toddler bed from my SIL.". She said that would be nice and then said "will you put it in your room?"
I said probably not as DD (then 8/9 months) was still co-sleeping and waking a lot so it would be better to put the bed either in the room that was DD's (though she wasn't using it at the time) or, if friend's DD was a bit lonely, in my 6 year old DS's room.
Friend hemmed and hawed for a bit then said "well please your DD's room and not DS's."
I asked why and she said "It's just in my line of work" (she is a therapist) "I have a different world view, and I'm so paranoid about DD being molested. It's nothing personal at all to your DS, I just have seen people's lives ruined in an instant, and if he got curious..."
I was so
I finally just said "well...if...um, you think that's necessary..." thinking WTAF. She then said her DH wanted her to ask, since our house was old, if there was any lead paint around. 
A few weeks later we went out to a movie and she drove me home. (She's rarely at my house because she lives a few hours away.) She asked to cone in and use the bathroom and I said of course, but warned her it was unusually messy. She went in, then called me in to speak to her.
Now. A word about the bathroom. It was very messy indeed, full of laundry because that is where are washer and dryer are and the dryer was broken. So laundry etc everywhere. It was very untidy but not actually dirty as I do wipe toilet/sink everyday.
So I go in and she says, waving her hand to indicate entire bathroom, "what are we going to do about this...because I can't sell this to DH."
I stared at her and then said, well, of course it isn't usually like this and even if it were, I would tidy before having guests, even a three year old guest.
Then it dawned on me and I said "well, of course I will tidy it anyway but...your DH isn't going to see it, you said you were dropping DD off before you leave."
She hemmed and hawed again for a bit and then said (and by this time, may I add, we were sitting in the living room which, minus the odd toy, was perfectly tidy as was every room BUT the bathroom :o ) "well...he said " I don't really know Cheerful...he said he needs to see your house before he thinks DD can stay here."

I should add, I have known her DH as long as I've known her. I have a drawing he gave me for my 21st birthday in a scrapbook. I'm 32 now. 
I was, again, stunned, so I just said "well that is ridiculous, of course he knows me but if he thinks he has to..."
But later talking to DH he absolutely hit the rood and said "no way am I letting
