What is sleep?

[Suicune's Fire]

I think I've pulled an all nighter like twice in my life, at birthday parties in my teens haha. But then I ended up going to sleep at like 7am so I don't know if that really counts. I used to stay up til 4am on the weekends chatting to friends online but I can't stay up past like 11pm these days haha. I don't like sleeping in anymore. It makes me feel kind of off for the rest of the day.

Definitely doesn't count. xD To me, an all-nighter is waking up as normal, staying up for over 24 hours and going to sleep when you normally would later that night (though an early bedtime is understandable xD). Like wake up at 9am, stay up 24 hours, then another 12 hours and go to bed at 9pm on day 2. Wait, is that just my definition of an all-nighter? O:
