I think that it is just poor manners of your house-guest to require an assisted bath at 10:30pm on a Sunday.
It's also rude for your own family member to also need an assisted bath at 10:45pm on a Sunday.
That's what happens when you are living with two naughty puppies and they decide to run outside and roll around in poo together for 15 minutes.
I just don't see the appeal, but I guess beauty is in the eye of the beholder.
