Nothing shows less consideration for others than to whisper and rattle programmes and giggle and even make audible remarks throughout a performance.
Very young people love to go to the theater in droves called theater parties and absolutely ruin the evening for others who happen to sit in front of them. If Mary and Johnny and Susy and Tommy want to talk and giggle, why not arrange chairs in rows for them in a drawing-room, turn on a phonograph as an accompaniment and let them sit there and chatter!
If those behind you insist on talking it is never good policy to turn around and glare.
The only thing you can do is to say amiably: “I’m sorry, but I can’t hear anything while you talk.” If they still persist, you can ask an usher to call the manager.
The sentimental may as well realize that every word said above a whisper is easily heard by those sitting directly in front, and those who tell family or other private affairs might do well to remember this also.
As a matter of fact, comparatively few people are ever anything but well behaved.
