No Job Posting Yet

So my former boss told me that they would be posting my previous position on Monday.  I had planned on reapplying and getting my old job back.  Problem is, Monday has come and gone and it has not been posted.  I wrote to my boss on Tuesday to inquire about the posting just to make sure I wasn’t missing it.  She said there seems to be a delay with HR and she didn’t know why it wasn’t up yet but hopefully it would be soon.  Well, now it’s Wednesday and still no posting.  I’m patient and I can wait, but I’ve really psyched myself up for the chance to go back to my old job and now the wait is a little bit harder!
