As anal as I am about being on time, I think it's kind of cute when her excuse for being late is "I'm sorry! I didn't like anything I tried on!", a la Brad Paisley's "Waiting on A Woman", https://www.youtube.com/watch?v=M-C-IbkuNWs. It's also kind of cute how they seem so anxious to please (NOT sexually), how they stress about wanting to do everything right for a birthday, Valentine's Day, etc. If they are in their early or mid 20s and still have the same stuffed animals they've had since age 5. If they try to get really into the things you are, i.e., sports, video games, etc. How they shift around while cuddling. I agree with kingofnature, I could go on and on :)
I knew a girl who would randomly fall asleep in the middle of texting or Facebooking, and she had a tendency towards being scatter-brained.
