Just ramble about this and that.

Haven't you had any interesting experience recently
or haven't you read anything impressive article in a
newspaper or a book?
Anyhow what's on your mind now?
Talking to yourself is also OK. 
 

I feel non-natives have some limitation in understadning natives' conversation. Listening ability is limited. Maybe if we are over 12, it's impossible to understand foreigners' conversation completely. But how can I improve my listening ability?
