I had a bad headache yesterday. That was why I was absent.

Why haven't you been showing up to work lately?

I feel out of sorts today. That well water is why.

It's such a nice day. Why don't you take me for a drive?

Why, I've let him win just to please him!

Why did you absent yourself from class yesterday?

Why don't you try to get your money back?

Do you know the reason why the sky looks blue?

Why don't you come to my house one of these days?

Why don't we drive out to the country for a change of pace?
