"You cannot delete your notifications yourself." Why not?

[John Chesshir]

It's nice to remove a notification once I'm done looking at it.  Why do we not get this option?

[Rodney Hughes]

I don't understand the scenario ..

A "notification" is an email sent to the various Users PC when something has changed in the system - it doesn't reside in Confluence itself.

Hi John,

I'm guessing you mean the notification in the Confluence Workbox? 

Workbox notifications will be automatically deleted after 2 weeks if you've read them, and after 4 weeks if you haven't read them, but there's no way to manually delete them.

This is a question I get a lot when I'm training people on Confluence, and I've never been able to find an answer.  There isn't a ticket in requesting the functionality either (at least, not that I can find).
