Explain?

"I don't care whether you have done something fishy, you sendiri pandai pandai la ha..."

***

I was like,
LOL?

Okay,
actually things are simple,
just now my bro wanted to use my laptop (without asking permission, get used to that),
then suddenly my laptop appeared with some graphical(?) error,
so he was like a bit weird with this and asked that did I do something "fishy" just now,
I said in a funny way that the error occured because he used my laptop.

Ended up he was like unhappy(?) since I didn't tell the "expected" facts..
He asked me the same thing again,
then I answered him I did not and I have no idea why.

Then...
he just said that epic sentence just because he thinks what I explained did not match with what he expected...

LOL WUT?

What else do I still need to explain??
Give me a break! @@

After you see this post,
you may not understand why I feel in this way,
sometimes,
I will have the same opinion like you when I see how my brother reacts...

Anyway,
brother always,
I forgive you.

*Peace* :)
