First new thing I learned of the trip...brazil is the only country in South America that speaks Portuguese instead of Spanish. Good thing it's just a layover!
Also, the guy who sat next to me on the plane told me not to drink the water, yet my water sterilizer gave me a green light...and then a red light. Guessing even a little green means it's a little ok...only one way to find out!
Current temps: a humid 85 degrees in São Paulo. I had to take off my jacket and already accidentally left it behind when I went to the baño. That was a test...so far the people are legit!
