If your wife has to wake up early, so do you.
This weekend my wife and I traveled to Chicago to visit my family. While we were there she went to the American Library Association Annual Conference for work. Each day she had to wake up at 6 AM in order to make the hour drive downtown and I got up with her each morning to see her off.
Even though my waking up served no real purpose, (we hit the snooze timer and woke up too late for me to maker her breakfast, and she really only had time to get ready and leave so its not like she even really got to see me) she really appreciated me making the effort to see her off.
