How can I get up later?

I find getting up early annoying because I always have to be bored until 12 noon because nobody is online to play Minecraft. I always get up at around 8 o'clock, usually between 12 and 1 o'clock. Is there any way to sleep longer? XD

Are you on vacation or why?

You can just do something different in the morning, you don't have to get up and play Minecraft right away. You could read, practice an instrument (if you play one - if not, start ^^), learn for school (or learn something outside of school stuff that you are interested in, e.g. A language) … There's so much what can fill your life doesn't just have to be Minecraft.

But find Minecraft better. And my sister often sleeps until at least 10 and playing keyboards is somehow not that much fun for me. School stuff? I'm on vacation, please don't mention the word school xD
And I don't like reading that much
