thanks a million to my very brave neighbour shin shin who helped me check out on the cockroach...
it is indeed behind the shelf. she says the feelers are still moving but more dead than not liao. and she scooped up the insect with a piece of paper carried it away mumbling 'it's dead liao, so poor thing...' the cockroach is so poor thing ah? it scared me until half dead lor... anyway when she got it out i had to stand far far away and couldn't even bring myself to look at it. one glimpse is more than enough to make all my hair stand...
but thank goodness now i can sleep in peace...
