Should I be happy or sad....?

Hmm.....
tomorrow back to kl rdy...
hmmm.....
sad coz leaving hometown,
sad coz have to pack things : P

happy coz can go back clean my room,
....

haih, life is complicated....
there always been unhappy and happy....
to get a full happiness, one must get sadness first...
so, without sadness, happiness won't be known....
but with sadness, it might involve life being brought to danger
sometimes having continuous happiness might make us feel that there are no happiness
but actually it is there but since it is continuous so we can't feel it much....
