A peaceful room can be shared by people who are enjoying different things quietly.

Company does not always mean doing the same thing at the same time. Two people reading different books in one room are still keeping each other company, and the ease between them comes from the absence of demand rather than from shared activity. Much of what makes a room peaceful is that nobody in it needs to be entertained or matched.

Try an evening where you sit near someone without organizing a joint activity. Bring your own thing, let them bring theirs, and notice whether the quiet feels lonely or comfortable. If it feels comfortable, you have found something worth repeating.
