[The Truth]

I have a question, too. It is about the apostrophe after an "s".

I learned that the apostrophe after the "s" shows the ownership held by more than one person. For example:

The Jones' dog died yesterday.

So because of this I have a pet peeve that has developed. When I see a "s" with an apostrophe after it just because, it bothers me. For example:

Mr. Jones' briefcase was left the building.

I'd love your feedback on this.
