I know my sister is at home and she's online at the computer/study room. So I decided to kacau her. I called her using the house phone. And in 3, 2, 1 'ALIAAAAAAAAAAAAAAAAAAAAAA'. You see, I know for a fact that she gets really annoyed if I kacau her. Tak kira la prank calls or repeating the same song for half an hour or singing some lame ass songs. Anything. Sometimes when I get really bored I'll change her ringtone and phonebook. She'll get so pissed off, her nose jadi kembang kempis. It's hilarious.
