Mencius - Book 2, Part 2, Chapter 2A

As Mencius was about to go to court to see the king, the king sent a person to him with this message, 'I was wishing to come and see you. But I have got a cold, and may not expose myself to the wind. In the morning I will hold my court. I do not know whether you will give me the opportunity of seeing you then.' Mencius replied, 'Unfortunately, I am unwell, and not able to go to the court.'

Next day, he went out to pay a visit of condolence to some one of the Tung-kwoh family, when Kung-sun Ch'âu said to him, 'Yesterday, you declined going to the court on the ground of being unwell, and to-day you are going to pay a visit of condolence. May this not be regarded as improper?' 'Yesterday,' said Mencius, 'I was unwell; to-day, I am better: why should I not pay this visit?'

In the mean time, the king sent a messenger to inquire about his sickness, and also a physician. Mang Chung replied to them, 'Yesterday, when the king's order came, he was feeling a little unwell, and could not go to the court. To-day he was a little better, and hastened to go to court. I do not know whether he can have reached it by this time or not.' Having said this, he sent several men to look for Mencius on the way, and say to him, 'I beg that, before you return home, you will go to the court.'
