Visit Omegle, and give it a spin. I'll wait here.
So, let me guess: you spoke with a Brazilian. A 19-year-old Brazilian. Or maybe even a 14-year-old Brazilian. Despite the fact that Omegle is not a Brazilian site (to the best of my knowledge), I definitely felt like the foreigner when I visited it. The OLD FART foreigner.
This site has some amazing potential -- I love the simplicity of the experience, and it's easily addictive. However: I have zero interest in speaking with anyone who isn't a grown-up, regardless of nationality. If I have one more conversation with someone who says "r u" instead of "are you," I will scream. If I have one more conversation about somebody's upcoming math test, I will scream. If I have one more conversation with someone who doesn't know yet what they're majoring in, I will scream.
I'll revisit Omegle in a week or so, and see if it's grown up at all. These things tend to improve exponentially -- if I wait a whole month to log back in, my parents will probably be on by then.
