Advanced list pages

I am hoping to do a “wp_list_pages” that will show that pages parents children…

I thought that possible having a negative depth would work, and failed miserably… perhaps there is some PHP function that could do this?

this is what I have thus far… just shows children:

<?php
	$children = wp_list_pages('depth=1&title_li=&child_of='.$post->ID.'&echo=0');
	if ($children) { ?>

<!--[if IE]>
<style> .highlight_2_col{margin-left: -00px !important;}</style>
<![endif]-->

<div id="children">
	<ul>
		<?php echo $children; ?>
	</ul>
</div>

Thank you,
