BIOLOGY is FUN....: Letih

Aku dah letih....,
kesedihan hatiku tiada siapa yang tahu.
Tolonglah berubah.........
aku dah letih menebalkan mukaku menahan malu.
Tolonglah berubah.......
Jangan biarkan lagi aku menangis lagi di khalayak kerana keegoanmu....
sungguh!
letihku sudah maksima............
tangisanku hari tu adalah yang pertama dan terakhir!
aku tidak bergurau
sungguh!
aku tidak bergurau!
