OK this has been bothering me for some time. Does Nelly have a medical condition or is there some reason she visits the WC so often? I once saw her go there more than 10 times in 1 hour and in a typical day must go to the smallest room 50 times a day. She's not taking anything in or out, she has a sink to wash her hands in the kitchen so I doubt if it's an OCD cleanliness thing so what is the explanation? Maybe that's were she receives her injections of happiness - and I wasn't being literal - because she is one of the smiliest people I have seen.
