11. Because you're throwing a Halloween party and right after you spend hours upon hours cleaning the house so your friends don't think you're a slob, you just have to clean it again after they leave.
13. NaNoWriMo. NaNoWriMo trumps everything. (OK, OK, not everything. Don't want my toddler to starve or sit in her filth.)
14. Because you're throwing a birthday party for your toddler (and you know unlike your friends, your mother will criticize everything if it's not clean), and the toddler doesn't care one jot that you cleaned. She never does. And she shows it by the shredded pile of wrapping paper after she opens her presents like a maniac.
