Sleep in a bed to change your spawn point. Did it once, on the first evening, and have never needed it since.
It got dark outside so I stayed in. Then it got light again and I was already comfortable.
Nine hundred days in the same square room. The torch has not gone out and neither have I.
Something is walking around outside the window. The door is shut. Not my problem.

I put down the floor first, then the walls, then the window because I wanted to see the weather without being in it. The bed went in last and everything stopped there.
People come in, place a chest, mine a bit of the wall and leave again. I watch this happen from exactly where you see me.
The bed is red. That is the only decision I have made in here.
The sun came back on its own. I want that on the record: I did not help.
Every world has one block you never move from. I am sitting on mine.
