well. i haf a simple one.
during bmt at nite dun haf lots of time to use hp. wat i did was to
put my fone below my pillow, and use handsfree. so when its lites
off, i will sleep on my side to hide the earpiece and use blanket
to cover the microfone. den toking v softly i can tok into the
nite! best i will lie facing the window so if sgt come i wil stop
toking jus in case.
there was once i lied facing inside, and was toking, den suddenly
discovered the sgt has come into the rm and was at the foot of my
bed! i tot this time cham liao but it seems he din noe i was using
the fone!
