What would you do when you woke up covered in blood?

Aaah!! Why am I covered in blood? Ogodogodogod. What happened last night?!
Okay first lets way the possibilities.
Is it possible that I am a werewolf?
No, probably not.
Maybe it’s my own blood.
No, I don’t have any pain and the amount is way too much.

Maybe I should retrace my steps. What did I do last night?
After dinner my friends called if I wanted to go out with them.
We went to a pub around the corner.
One of them got so drunk that we got kicked out.
Well, actually he got kicked out and…
No! I shouldn’t digress. Focus! Focus! What happened then?
He suggested we go somewhere else. He had the keys of a closed building.
What was it? What was it? What was i…
Ah yes, a paint factory.
What did we do there?
What? What? What? What?
One of them started fooling around with… with what?
Buttons. A panel full of buttons. What were they for?
They were emergency buttons. But what did they do?

Of course. They were emergency release buttons.
This isn’t blood! It’s paint.
