Some of them may be justifiable, some are not.

I am not so rich as I should like some people to believe.

It is so much easier to live well, you know, when people believe that you are rolling in money.

Still, I am by no means a pauper.
I cannot afford to take Grantham House, but neither can I afford to go on living here.

I have decided to make a change, to try and economize, to try and live within my means.
