Don't I know better?

So I get a call at 3:30 this morning from B, telling me wife J (who is 42 weeks) is having contractions that are 3 minutes apart and lasting for a minute. They say they are getting ready to leave but will call when they are out the door. I immediately hop out of bed, make coffee wash crust out of sleepy eyes. 

It's now 4:49. I could be sleeping. I am typing instead.
