Release me, please.

I'm so bloody tired.
Standing 5 hours straight without drinking and eating at all, got really busy with the customers. I didn't even get a chance to catch my breath. The worse thing is, the workplace is not fun as it used to be. So I decided to quit. I have no reason to stay, afterall.

And the conversation goes..

Me (A): Hi Nicole are you busy?
Manager (N): No, why?
A: Emm. I just need to tell you that I wanna quit. Next week.
N: (widely opened her eyes) Whooottt? Why? Why? Why?
A: ............... (seriously, I didn't know what to say, so I came up with an excuse that later turn out to be so wrong). Well, I'm going to move to Cannington next week. I think it's too far away from work.. So I...
N: Hey I live in Cannington too! Which part of Cannington do you live? I can come to pick you up, so we'll talk about it and re-arrange your roster on this friday, okay?
A: Well...
N: (she left already).

Oh. Funny. Now I have to make up a better excuse.
