wp_list_page – exclude current page

Hi

I have searched and tried various plugins and snippets to create a nav in my page.php template that shows the child pages, *siblings* and parent pages… not sure my terminology is right there… but my problem is trying to exclude the current page from the this is what I’ve got so far:

I’m using breadcrumb nav-xt plugin and a wp_list_pages

<li>
<?php if (class_exists('bcn_breadcrumb'))
{
// New breadcrumb object
$mybreadcrumb = new bcn_breadcrumb;
// Assemble the breadcrumb
$mybreadcrumb->assemble();
// Display the breadcrumb
$mybreadcrumb->display();
} ?>
</li>
</div>

<?php
if($post->post_parent)
$children = wp_list_pages("title_li=&child_of=".$post->post_parent."&echo=0"); else
$children = wp_list_pages("title_li=&child_of=".$post->ID."&echo=0");
if ($children) { ?>
<ul>
<?php echo $children; ?>
</ul>
<?php } ?>

I have read http://codex.ww.wp.xz.cn/Template_Tags/wp_list_pages

and found

<?php
wp_list_pages('exclude=17,38' ); ?>

but cant figure out where to put the exclude and/or how to exclude the *current* page in the wp_list_pages

if that makes any sense, please help me out?

thank you
