List specific pages and sub pages

Hi Guys,

I tried to looking around how to list specific pages include the subpages.

Currently i’m using:
<?php wp_list_pages(‘include=65,90,92,84,82,88,80,86,61,78,72,74,67,76&title_li=’ ); ?>

this will show all the list of course with the subpages inside there.

Using this syntax
<?php wp_list_pages(‘child_of=65’);?>

Only showing the child pages and I need also the parent page

Is there any way to do this ?
Just want to avoid if later I added new sub pages I dont have to update the theme again.

Thanks in advance
