The following part is a true story:
I was playing on my world when my mom yelled "###### TIME FOR BED" I ran to my bedroom, turning my minecraft off.
Later in the morning I got onto minecraft to see a giant white building, quartz outside my house. Horrified I satred... and turned it into a museum
The rest is fake:
Someone typed in chat
Monument: Player, you have used my building unwisely
Me: *Staring at staues and realizes chat* Wait this is singleplayer? Howd you get in

Monument quickly closed my minecraft but I found a YouTube tab open.
