Understanding fluent speech I've been learning English for more than six months and i've noticed that real conversation is much better than video with subtitles or something else. I'm living in the country where the native English speakers stay so rarely. I have heard real conversation only three or four times but i didn't participate in them. The last case was at my work. Two workers were talking to each other and i understood their well despite of that then i had studied for approximately three months. So, i'm still making a lot of mistakes. Judge me strictly ;)
