I like taking quiet bus rides in the evening, when the top deck is empty and devoid of other human life.
The moving bus provides interesting scenery as it goes through its route.
The air conditioner, the right cool temperature, as I look out at humid Singapore.
The setting sun provides just the right amount of light to make everything look beautiful, and just the right amount of reading light.
I dislike bus drivers who can only speak mandarin and worse still, are unable to tell you if their bus route passes by a certain place -.-
