I bought a book.

I bought a book yesterday.

Did you buy a round trip ticket?

And a man says very excitedly, I was in your gas station a while ago, and I bought this jewelry for my wife, and I can't find it.

So I wrote a book about this in '93, but as I was finishing the book, I had to do a little bit of typesetting, and I was tired of going to my local copy shop to do it, so I bought a computer.
