I can relate. I've slept through a class I had a really important presentation in because my alarm had been set for pm. Yeah, my fault, but I think this is a valid FML.

That sucks! Can you retake the test?

lol, damn, that sucks. Sadly I've done the exact same thing... twice.

Doesn't your clock have the little light for PM?

Thats why you always set your clock to military time.

How do you not notice that it's 5pm instead of 5am? Are you a drug addict or an insomniac? Or just plain unobservant.

thanks for bringing down the class average and therefore making my score higher, I will remember you when drinking courvoisier on my Yacht. for someone to win someone else must lose- thanks for covering this one.

jajaja eso mismo me pasó una vez cuando me dormí una vez a las 4pm y me levanté a las 5pm pensando que eran las 5am, si no eran las luces juro que creía que era otro día

That happened to me twice in college. Lack of sleep and stress give you a lot of surprises in life.

So what time did you go to sleep that you slept for so long without waking up once or looking at the time...?
