So what if it's Friday

There are days / times when you get up in morning with a heavy head after just about 4 hours of night sleep (Working late hours). Don't feel like doing anything.. talking to anyone.. don't feel like working.

But it's Friday yar.. SO what?

If I have a foul mood, then how does it matter it's Friday or Monday or Tue?

Why do ppl keep saying.. It's okay boss, its Friday chill, relax.

Friday doesn't allow me to relax when I have P0 (highest priority) work to finish with a bad bad mood.

That's when I say - So bloody what if it's Friday.
