i have been talking with people too serious here and i do feel awkard when i make a mistake, but also i have been talking with people so funny and confortable to talk, you know.. more informal.. that i dont even care if i say something stupid! i take this as a solution! sorry for my bad english! i talk spanish. I hope this helps you and if you want someone to talk silly things and learn spanish at the same time, contact with me! jaja xoxo
