Burundi is in Africa you twerps
Polls aren't fact, just an attempt at getting insight. It has a lot things to factor in which makes it not very reliable (to the letter) like who you asked, what, how, when etc. There is always a grain of truth to it though it can give you a general idea (if all people questioned were done so in the same manner). And it might give you a different answer than you seemed to have been asking.
(like if you ask a kid if they are hungry when you hold something they don't like in front of them, or when you ask it when you hold a treat, the answer will differ dramatically, though the fact of how much and how long ago he had eaten hasn't changed))
Also being friendly or kind is not the same as being happy.
(I might even go as far as saying there is an inverse proportionality, many times people that don't have it easy in live are often very kind (and I don't mean when you aren't allowed to watch your favourite tv show or when your sports-team has lost.. )
Is... Is this comment MEANT to be satirical, or..?
