auxiliary have

Hi, navigator!

You had better fly is a statement, whereas Hadn't you better fly? is merely a suggestion.

The neighbors would be indignant if you gave all-night parties is correct, and perhaps better for formal writing.

You'll have the neighbors complaining if you gave all-night parties is not quite correct anyway because the verbs don't agree. It should either be "you will have...if you give" or "you would have...if you gave".

This construction, "to have [somebody] doing [something]", is more colloquial, though perfectly acceptable. It is particularly characteristic of Irish English where it is a memory of sentence formation in Irish Gaelic.

Hi syntinen, I meant give . Hadn't you better fly? is a suggestion,

but can't we consider it as an advice like you had better fly?.

Thanks

We use the future perfect to talk about the completion of something, the length of time something has been going on measured against some point in the future. These future points often revolve around important personal dates like anniversaries, length of time on the job, etc.

By Thanksgiving this year, I will have worked here for 20 years.

Come July 1st we will have been married for 40 years.

Try one for yourself, Navigator.

You have to be careful because there are uses that look like the future perfect but they refer to finished events.
