Display subpages of page "A" on page "B"

Hello everyone,

I would like to display the subpages of a parent page as a list on another one of my pages. I don’t want to list all the subpages in my site though, I just want to list the ones under that specific parent page. After looking through the forums, the codex, and doing some google searching I haven’t had any luck figuring out how to go about it.

Might anyone lend me a hand?
Thanks.
