Let me share a joke.
An English priest visited China. As a part of his daily service, he visited hospitals, went from bed to bed and prayed for the patients' recovery; he also blessed his good wishes to them.
One day he was standing closer to a bed where a Chinese was lying ill. He was awake. As the Priest kept praying with a smiling face intently looking at the patient, the patient started shouting aloud in Chinese and gesturing something vehemently; the priest could not understand a word, but thought the patient was in some agonizing pain and he continued to pray.
Right before his eyes, the patient died in a few moments. The priest was shocked. Nurses came running in. The priest managed to remember the few words that the Chines repeatedly shouted before dying. He repeated those words to the nurses and asked "Would you mind telling me what those last words mean?"
The nurse replied "He said 'Hey move away; you are standing right on my oxygen tube".
