“…denim is being used as a code word for linen…”
Really? Code? Secret code? CIA? Are we talking espionage? I am at a loss. Please clarify.
CIA? Who said anything about CIA? Have you never heard of any codes besides the CIA?
It is a normative social standard to refer to certain things by “clean” names. Do you say “bathroom”? Is it a room with a bath? Does it always have a bath? Are you in the CIA because you don’t say toiletroom?
