I decide.                     I make up my mind.
It is easy.                    I can do this with my eyes closed.
Hurry up                    The clock is ticking. Let’s go!
I don’t know               I can't remember off the top of my head. I'll get back to you on that.
I’m fine.                     I am on the top of the world.
It is boring.                It is like watching grass grow.
You are right.            You’ve hit the nail on the head.
I love you                  I'm head over heels for you.

I like it                       I’m very interested in doing and learning about it.
I understand             I have got the gist of this.
You are wrong          You should think twice on that.
I am sad.                   I am down to the dumps.
I am happy.              Having a whale of a time.
I am busy.                I have a lot on my plate.
You are stupid          There isn’t much between your ears.
Good job                  Couldn’t have done it better myself
Good night               Let’s start counting the sheeps.
I am just joking        Just trying to take the Mickey!
I am not sure.           I do not believe this is true.
