The People in Argentina and the life here

I've noticed that people here aren't nearly as nice as people in the Caribbean. When you smile at them, they look at you like you're crazy. I thought it was normal to say hi and smile at people but apparently it's not ok here. lol. Not many people smile here either, it's weird. But everyone here looks European so sometimes I feel like I can speak English to them because they all look like what it looks like in america. EXCEPT there's no black people here. I truly have only seen two since I got here. Anywho, I've been taking the bus everyday, looking like a local. But here they have no sense of personal space because the buses are so packed all the time. lol. And you also don't have to wait more than 3 minutes for a bus because they come constantly, sometimes there's 4 in a line picking people up. But they drive like bats out of hell and when you're getting off, the chances are that the bus is still moving. lol. I haven't taken the Supte (subway) yet but I will definitely write about it once i do. That's all for now. I'm getting ready to go to a club tonight so I hope all goes well! Buenas noches!
