Is the man inside or outside the house?

It's an edited photo. Both options are illogical

You couldn't see the roof if he was inside.

I think most of them are missing the perspective. Just imagine that two of the four walls of this room have been removed for you to have a look of the inside of the room. You wouldn't be sticking notes on the outer wall of your house, would you ?

The artist got high

Under

I love these kinds of things. Have you checked out Rob Gonsalves' art? Same style.

Obviously inside, he couldn't have laid a rug out in the wild and then put a chair & table on top of the rug ?

he is a drug addict. That's all I can say

He is on the patio

Both.

Thanks for the honour.
