What they say and what they really mean

Not bad
Good or very good

Quite good
A bit dissappointing

Perhaphs you would like to think about..../It would be nice if you....
I want you to do this, but am open to comments. If I hear nothing I will assume that you are doing it

Oh, by the way......../Incidentally..........
I am about to get to the primary purpose of our discussion

I was a bit dissapointed that you......./It is a pity that you didn't....
I am most upset and cross with you

Now for the Jems!

I hear what you say
I disagree and do not wish to discuss it any futher

With all due respect
I think you are wrong (or a fool)

Very interesting
I don't agree/believe you

Perhaps we could consider some other options
I don't like your ideas

I'd like to think about that a bit more......../I'll bear it in mind..........
I don't propose to do anything
