Pages->SubPages

I have the theme twentyten.
I use the navigation bar at the top for my pages, which include subpages.

For example:
Telephone List
-Telephone Extensions
-MSN Addresses

However, not ALL my ‘pages’ have content, just the subpages. The ‘Telephone List’ page is empty, but the ‘Telephone Extensions’ has the content.

How can i manage this?

I could create an intro for the ‘Page’ but i think it’s a waste of time!

Does anyone have any suggestions as to what i should do?

Some pages don’t have SUBPAGES so this will not be something across the site. Well, i think only the HOME Page is a single page.

Any ideas?

Thanks!
