לא יהא אדם ער בין הישנים, ולא ישן בין הערים. ולא בוכה בין השוחקים, ולא שוחק בין הבוכים. ולא יושב בין העומדים ולא עומד בין היושבים.
One should not be awake among the sleeping, nor shall he sleep among the awake. One should not weep among rejoicers, nor rejoice among weepers. One should not not sit among those who stand, and not stand among people who are sitting.
Question: Does One should not be awake among the sleeping require (Derech-Eretz-wise) that (whenever possible) one should not do anything in a room where others are sleeping (even if it would not disturb their sleep), other than sleep?
If somene wakes up in the middle of the night and can't fall back asleep, and others are sleeping in the same room, may he turn on a small light (which would not disturb anyone's sleep) and read in bed or must he leave the room?
Does nor shall he sleep among the awake require (Derech-Eretz-wise) of a person to arrange for someone to wake him up no later than the other people who are already awake in his room?
