calculus

when you use your bag to reserve a seat, you probably think that nothing in your bag is valuable enough to be stolen. and yes, the things in your bag probably have no value to anyone - precisely because you take out your wallet and handphone when you leave your bag there.

but it's when you really lose the bag that you realise how important those worthless things are to you.

losing a diary book may have been the scariest thing ever. it jolts you so deeply, but when you get your book back it's like hugging a teddy bear all over again.
