I've been married for over 17 years. It's long enough that often we know what each other is thinking. Sometimes we can finish the other's sentence. It's not long enough to actually look like each other yet, give us another 10 years.
But occasionally we learn new things about each other.
I know Olaf doesn't like amusement park rides, not even the ferris wheel. I just thought it was because he has motion sickness problems.
I found out, while at Disneyland, that the guy is more afraid of heights than I am! How did I miss that in the last 17 years?
