Duhhh

Passing through the toll so i wind down my van's window, holding on the card and touch the 'touch n go' machine few times but still the bar does not open. I was sitting on the van, still touching it gently and patiently, still nothing happens. Then i look at my sis next to me and i was talking to myself, "it must be the machine's problem", while i'm still holding on to the card and suddenly we broke into laughter because we realised that the card that i was holding all the time is not the 'touch n go' card but it is my Maybank card. *Duh!!*
