You can walk into any room and scream. "THIS WHOLE THING IS A FARCE!", and it's entirely appropriate every time.
@RickiTarr
Not if you walk into a crowded theatre while a play is going on. If the play in question is, say, a tragedy and not a farce, you'll just be wrong... and if the play in question IS a farce, you're just disturbing players and audience alike to tell them something they already know.
@DinaMNealey All plays are kind of a farce
@RickiTarr
See the second part of my response for that. ^_^
