Usually I take taxi from home to office. Now and then, if it is not so urgent, I might consider to take the bus. The route is exactly the same, so be the traffic. The fare is less than one tenth. The problem is not matter when, the bus is all squeezed with passengers. No matter how cold the weather is outside, it is sweaty hot inside. It is not pleasant.
