Opposites Attract

I have to make a confession. I am a morning person. I never wanted to be a morning person. But it happened. I'm almost to the point where if it is after 7:00 a.m. the morning is 1/2 over. I know I am sick.
Now enter my wife. My wife is not a morning person. Far from it. My wife thinks if the day starts before 11:00 a.m. it is way too early.
Needless to say this creates some interesting events. Like me up in the morning ready to go and wanting to talk to Heather and Heather responding "huh?" Or Heather trying to talk to me a night and me responding "huh?"
Now I know we are not the only opposites like this. I just always have wondered why these things happen. Oh well.
