I think i seriously hate this phrase ' how i know '
come on, its rude right? when someone says that..
imagine you ask someone a question and the person reply ' how i know '
you will feel like asking the person to ' f off ' and slap the person right?
what i think is, this reply will be better ' i dont know wor '
sounds so much nicer and better right?
therefore, i will repent myself and stop using 'how i know' too :D
