Talking in riddles

Every day this week I have been checking my emails... except today! For some reason I thought it was a Saturday, therefore no office type work should be done. That is until I thought I might have an email from a friend I haven't heard from in a while.
Instead of that I had the email I have been waiting for, asking if I would like to go out next Saturday (Like helloooo!!! Of course I do!)
That said, If I get a good email Monday or Tuesday I will he saying No I don't want to go out next Saturday after all!
Confused? Ha-ha, with any luck all will become apparent.. very soon!
Hey Northern Bird, Gimme some of that green plant! .....(four leaf clover I mean, just in case anyone thinks I mean anything else!)
