It's very interesting. I think Americans waste a lot of things. Others are wasting things too though. We can all save more paper I think. I don't know how many paper towels I use. I've gonna check next time! Maybe shaking your hands 12 times makes a mess though? Water can get every place. LOL!
I thought before it was "waving your hands" and shaking hands for when you meet new people or say hello to people. So I learned a new vocabulary today!!
I like this talk, it's short and I understand the meaning of the talk. I think this is a really great idea. I'm coming back again to practice again.
