How to respond...?

办公室点滴。。。

Q: "Why are you here?"
A: "To work..."

Q: "What are you doing here?"
A: "Working..."

Q: "What brings you here?"
A: "The bus....?"

Q: "I haven't seen you for a long time..."
A: "Neither have I..."

Q: "Oh, I didn't know you are back to office..."
A: "I know..."

Q: "Hi girl, tell you what..."
A: "Hi Auntie, what..."

如果一切竟在不言中；那又何必挂齿。。。
