Mood swings?

So yest just work & home.
Mlm toggle between Gaduh2 Sayang on Suria & Misi XX on TV3.

I just don't understand why some people have mood swings??
And they shout at people?
Huh??
what did i do wrong, man?
At least if they keep quiet & show the face "i need to be alone", o.k laa I can understand..
And some juz keep mum?
And left me to wonder, now, does she needs my help or doesn't?
Clueless beb!

Betul laa, manusia nie bermacam2 ragam.
Think I better keep to myself.

And better don't say, I'm not concern!
I cut off ur tongue!
