When C is cleaning, she is doing it with some aggresion. It looks like she is taking out her frustrations to me.When Allsion does it, it seems to be more of the martyr method. You know, like " don't worry people, even though I am the one around here that just had major surgery, I'll take care of this mess" And I'll do it with a big smile on my face that says, I'm fine, everything is good.
I think the rest see these two cleaning and are glad somebody else is doing it.
