Day off

Woohoo! I can go for the club crawl thingy tomorrow. Yes ah!! Am i more excited that i'm going for the club crawl or more excited that i'm getting the day off? Well, the truth is... Getting the day off. Hehe... I had to write a letter to my supervisor so that he'd approve it. Here goes:

Hi NK,
I'll be having a cca orientation in school tomorrow. It will be an all day event therefore I won't be able to come for work. Hope it will be alright and your approval would be appreciated.

Thanks & rgrds,
Adlina

So, one day off. Left with 26 working days. I need to find other ways to get an off. The next plan is to get sick. Any ideas how?
