Here is a brain exercise that everyone needs to do. It is about hypothesizing based on clear indications.

Look at picture 1. Would you guess that a tv belongs in that room? Would you guess this room is for watching tv?

Look at picture 2. Would you guess that you cook in this room?

Look at picture 3. Would you guess that you poop in this thing?

Look at picture 4. Would you guess that you poop in this hallway?

What's that? There's no indication you're supposed take a dump in the hallway? That's exactly what everyone did in the Palace of Versailles before proper toilets got installed. (1/2)
