Dated a girl once where our work shifts differed, she basically would leave for work about 4 hours before I would. She also didn't like to get much sleep herself. Though she'd take a nap when she got home from work while I was still at work. We'd then spend the rest of the day together, and I'd wake up and keep her company when she was getting ready for work, and then I'd try to get a couple more hours of sleep before I had to leave for work.

By the end of the week, I'd be so tired from not having regular sleep, that on my days off I would pass out for about 10 hours... this upset her greatly, and she'd go off on me and stay mad for a day or so. Because I was sleeping...

That was the single most annoying thing I've ever dealt with.

Some people just want a reason to be upset.
