I'm the kind of person who likes to make to-do lists. That's just one way of being my organized self.
Sometimes, while I'm in the middle of something I'll remember that I need to add a few things to my to-do list and because I don't have my pen and to-do notebook (the notebook where I put my to-do list of course!) I make acronyms in my head to remember for when I'm free and am able to write it down in my notebook.
It sometimes goes like this PMM for Phone call, Mark books, Meeting.
While I was on the train this morning I made an acronym again: Forward mail, Medical cert, Leave procedure...FML...hahaha...oops!
