*One of my colleagues is going to America but he hasn't thought about his job & even language! He doesn't know anything!
Somedays ago he asked me some questions about English & I said it has lots of vocabs but you can learn it easily if you can. At first it'll be difficult a little but after some months you'll learn more & more easily. You should just give it a try.

He asked me if I can speak it fluently?
I said no!
I think I can understood myself but I don't want him to ask me teach him. So I said no.
