You'll miss Dick's coming of age, won't you?
There are to be high doings.

Mr.Hardcastle is too mysterious and pompous to live.
One can't get any thing out of him but just 'My son Dick doesn't come of age but once' (as if we thought it was a yearly occurrence), 'and we don't celebrate it but once.' But I got hold of Dick privately and wheedled it out of him in less than no time with a piece of soft gingerbread.

It's to be something _stunning_.

His father wanted to do it up in English style, dinner to the tenantry, and all that sort of thing, only unluckily there wasn't any tenantry, and he had to abandon the benevolent role and take to a jollier one.

He won't show off as well, but we'll have a deal more fun.
