I have only seen one real bidet in my life. That was when I was a teen visiting my friends large Italian house. I couldn't figure it out.
Last winter in Asia, particularly Thailand, we noticed the hose in every toilet. Not one was without. After months of this we had to go back to Canada and were feeling weird about not having one anymore. Marc said basically what you said. We clean everything with water not paper.
The knife and fork routine was introduced to me by Marc's German parents. I used to get in trouble for not setting the table correctly. I grew up getting the food to my mouth any way that it would get there. I can't stand the formal dining environment. I learned how to use chopsticks not too long ago. I try and try then just grab a fork.
I really enjoyed your video!
