On the other hand, do not whisper to any person who chances to be in the room.

Whispering arouses the patient's curiosity and suspicions, and, if he be asleep, the sibilant sound will pierce his slumbers and awaken him.

Let all remarks be made in a low-pitched undertone.

Never, even at the risk of causing offence, allow discussion of any subject to occur in the presence of the invalid.

You may imagine that he does not mind it, that his mind will be diverted; but the argument ended, there may be noticed a flush on the cheek and a rapidity of breathing that bodes ill.
