Oh Panda, so many things...
The young girls making video blogs cracked me up. But not as much as "Here, I could put you in this oven. But I will put you in this toaster." That was priceless.
I think the cicada thing is that all of the cicadas did not go into the Earth for 17 years ALL at once. Every year, they go into the earth, and those cicadas will not be back for 17 years or whatever it is, but the following year, the cicadas that went into the earth 17 years ago (not last years cicadas) are back. So every year, you have 17 year old cicadas coming back. It wasn't a mass exodus.
In NYC anyone who brings a travel mug or refillable vessel of some kind into a shop to get a refill would be looked at like some crazy psycho green hippie suburbanite. I was in Starbucks on Columbus Ave, and someone tried to do that, and the girl behind the counter refused to touch it. She looked horrified and said, "There is no way in HELL I'm touching your dirty dishes from your house! EWW!"
However, out here in upstate NY, people do it all the time. Personally, I would never. I think it crosses that line between private and public. Or like you said, private and personal, hehehe. This was hysterical.
