I work in a 20-storey building. You can only imagine how many people works in the same building. Hence, it is normal to NOT know most of the people that you share a lift with when you come to work and also leave from work. To have more than two people in the lift is alright for me. However, I do feel akward when there is only two of us because there would be this akward silence and none of us know where we should be looking. This gets weird especially when you greet each other before you go into the lift. It is as though I feel the need to "continue" the conversation after greeting the other person. But what can I talk about? The weather perhaps? Or the traffic jam? Or their children???
