A school bus is meant to be yellow. Not just because the colour is attractive (OK, that’s the main reason actually) but because of scientific reasons. Unlike the kids inside it, a school bus is expected to behave. You’ll rarely see it meandering on the road or jump a signal or two. It follows all the rules and maintains decorum even in the most frustrating of traffic jams. In an ideal world, fellow vehicles would let a school bus go ahead but then Indian motorists seldom allow even an ambulance that sort of special favours. One more thing is similar to a school bus and an ambulance: phone number on its back. In fact, you are encouraged to call up the number in case you notice something off. What would be interesting though is to notice a school bus misbehave for a change. Like speeding, for instance. What’d be more interesting is to call up the number only to hear, “I’m driving right now, call me later."
