Down the hatch!	Can I take a look at your paper for a minute?	Are you going to the English lesson tonight?	
Shall we have Chinese food or Japanese?	You must be over the moon at winning all that money!	I need more money but I really don't want to do another job.	
Do you like my new 
 Internet phone? It's a special deal. Only $1000 a month -  unlimited use!	Thanks, but I'd rather do it myself.	You've put on weight
since I last saw you.	
I suppose you've heard about the boss and that girl in accounts!	We've changed the font size to make it easier to read. What do you think?	My English is almost native-speaker standard, actually.	
Mind if I sit here?	Your wife (husband) looks nice today.	Fancy a walk?	
I work harder than most people.	You'll never guess who I saw
drunk outside a bar last night!	I'll manage your finances for you. Just give me your bank statements and leave it to me!	
I've got to lose weight but there's no way I'm giving up chocolate.	What do you think of my new Rolex? I got it off this guy in the pub.	Bottoms up!	
Minibus? Or shall we take the train?	It's very kind of you to offer but I think I'll go on my own.	I've been rushed off my feet all morning!	
Alright if I use your pen?	Wanna buy a Gucci bag? 
Genuine! Only $500. Let's say $450 to you as you're a friend!	I've put a bit more sugar in. Try it. What do you think?	

Cheers!	I'm easy.	I can't be bothered/	
Please yourself.	What are you getting at?	You bet!	
Be my guest.	Over my dead body!	You can't have it both ways.	
I'm all ears!	That's more like it.	You've been had.	
It's all go here.	I wasn't born yesterday.	I'll take your word for it.	
You could have fooled me.	There are no two ways 
about it.	You can say what 
you like, but..

Note. These examples have been chosen to help illustrate the use of the response. However they are not the only responses possible to the original statements or questions or even the most natural.
