We must think continually of other people.
We may not seek our own pleasure in any way without asking whether it will harm or mar the comfort of some other one.

For example, we must think of other people's convenience in the exercise of our own liberty and in the indulgence of our own tastes and desires.

It may be pleasant for us to lie late in bed in the morning, and we may be inclined to regard the habit as only a little amiable self-indulgence.
But there is a more serious side to the practice.

It breaks the harmonious flow of the household life.

It causes confusion in the family plans for the day.
