What happens when someone who loves thought experiments attends a soft-skills training that feels like déjà vu

Instructor:There's a glass in front of you.It's half full of water.What comes to mind?

Me:Let's prepare an enormous glassand pour the water into it.The water level is now under ten percent.Does that make you sad?Now let's prepare a huge number of tiny glassesand pour the water into them.Every single glass ends up full.Does that make you happy?
