According to Carrie

Things Carrie understands:

1. Being single is like being a social lepur.
2. An overly neat fridge and pantry may be the result of sexual impudency.
3. If the man is tipsy, it isn't coke in the bottle.
4. Men don't take subtle hints. Or very explicit ones, for that matter.

Things Carrie doesn't understand:

1. Why Brooks Laich seems to continually try to hold her hand.
  1. Introductions
    But he was already on his way over to him. This was one introduction I didn’t want to take place.
  2. It's Okay to be Single
  3. It's a Woman's Job to Put a Man on Edge
    After a brief look to me, he sent Mike a knowing look. “To show Carrie what every woman in Washington sees in me.”
