This may sound crazy and totally insignificant- but I need to learn how to keep a cleaner house.
My husband would do anything in the world for me. He stands by me no matter how deep my depression gets, he treats my kids from my previous marriage as his own (would have adopted them if their father were not in the picture), and basically takes care of all of us. His only fault is that he snores loudly and can be compulsive about cleaning... That's the only real argument we have. Silly, huh?
But having an organized house means a lot to him - it's the way he grew up. So this is where I feel I need to improve the most (and I have plenty of room to improve here, too!)
