I usually find myself wanting to do more things at night, which can kind of put a damper on being able to do things with people when they have to work early.
I am a night owl, too, since I stay up late at night.  Sadly, my current job causes me to get up early.  Never enough sleep.
That's annoying.  I always end up going to sleep after my wife.  She doesn't understand how I can stay up so late.
Your wife must be a lark; or an early bird.  I don't think night owls and larks can understand each other's sleep patterns.
