In somewhat of a defense for CalPeg, CA is dirty. I cleaned my windows both indoor and out more in the two years I lived in CA than I did in our last house in Texas. I don't know what it is about CA grime and how absolutely filthy your house gets even a day after you clean but CA is gross.
Her vase is filthy as well, that I'm not going to defend. CalPeg...wash your vase. Also, be mindful of your background. If CalPeg had clean windows normally she would have caught this before she took the picture.
