Well, a few months ago, I was at a Sleep-Over at my friend's house with three other friends.
We sat up talking and playing the Wii and our DS' to about 11 PM, afterwhich, we got tired, went to the kitchen, had a drink of juice, then went to bed.
We sat up talking to about 3 am. And eventually, we all fell asleep.
That was one of the times that I can remember, but after some talking to friends, I rememberd this;
It was in August, and I was staying at another friend's house.
We had went to the swimming pool that day, so by the time we got to his house, we were already pretty tired.
We decided that we would stay up playing Pokemon, go on the internet, and talk. Eventually, we both got tired, and we decided to call it a night.
My friend fell asleep within about ten minutes, but I couldn't fall asleep. I tried playing tricks on my friend to resolve my boredom, but still no sleep.
I lay awake until about 5 am, and then, I began to fall asleep....that was until, the birds started squaking!
I covered my ears, fell asleep, and woke up like a bear about 2 hours later.
If I ever stay up late, I wake up extremely grouchy the next morning. I'm not a morning person at all.
Another of these events was when my school decided to take a trip to Scotland. we had to get up at 5 AM in the morning, go to school and get the bus to the airport. Suprisingly, I wasnt grouchy that morning.
The world is quite peaceful at 5 AM. But in saying that, I took a few 30 minute naps on the way there and back.
But, all was not well. The trip was not very fun. But I enjoyed it despite everything else.
But, getting back to the topic at hand, the longest I have stayed up is probably to about 5 AM to 6 AM in the morning.
