Waiting for Bus

Went home after work at around 7 plus today. Came out from the MRT station and thinking:"Should I walk home or take a bus." Normally, I'd walk home but strangely today decided to take a bus.

Waited for quite a while (>10 minutes) and no sign of my bus coming. Wondered if I've made a wrong decision... But what can I do, since I have already strarted waiting, I know the bus would come eventually... and of course it did some 5 more minutes later...
