Why do I feel like I'm in school?

OK..

3. I go to the forum and read the posts
4. I find that even though I published the post, now that I've read it, I dont want to publish the postbut want to hold it for a period of time for whatever reason.so I unapprove the post (so far so good?)

THEN after a minute or 3, I delete the post from the control panel.
