Miss Manners: Don’t stand until curtain call ends

DEAR MISS MANNERS: We need major publicity to get across a matter of etiquette for concert and theater attendees: WAIT UNTIL THE CURTAIN CALL IS OVER AND EVERYONE HAS HAD A CHANCE TO TAKE THEIR BOWS BEFORE STANDING. ONLY STAND AT THE VERY END — AFTER THE PRINCIPAL ACTORS TAKE THEIR BOW.
