Thanks everyone!! :)
Yes, I was desperate haha but now I'm very dissappointed because I went to the airport, I got information from someone who works for the company that brings Coldplay to Argentina, but I wasn't able to see Chris because they got out by a private access as it seems, I waited and stayed at the airport for more than 4 hours...I also went to the hotel on wednesday but they went out to sign autographs yesterday. I'll see if I can meet them before they leave Argentina! Today is the big night, I'm very very happy!
Greetings to everyone!
