Folder Question

Hi

I have tell a friend pages on my site that I would like to add to my robot.txt file. The url is formatted like this:

http://www.mysite.com/Listing/Friend/pagename.html

So I can I add

Disallow: /Listing/Friend/

But the question I have is it won't block /Listing if it is not followed by friend will it?

For example I have other pages like http://www.mysite.com/Listing/3_Bedroomed/pagename.html that I don't want blocked

Thanks in advance

Dee
