Will you be damn angry when your brother suddenly bring a friend back from don't know where in midnight ? and yet he can tell you , "my friend need to sleep , do you need your fan... blah blah blah ? "
What thee hell ! Your friend need to sleep , my business is it ?!
Your friend need to sleep then i don't need sleep huh !
In the first place , you didn't even say your friend is staying over tonight !
So you cannot blame me for not lending you this and that !
