Here is a transcript of a dialogue from the WWII film Greyhound. In it, the commanding officer of the convoy and his executive officer discusses how to word their distress message.
Cdr. Ernest Krause: Do I break radio silence with a message to the Admiralty? Or does that let the wolf pack know just how vulnerable we are?
LtCdr. Charlie Cole: What would the message be?
Cdr. Ernest Krause: “Help needed urgently.”
LtCdr. Charlie Cole: No. “Help needed.” That means “urgently.”
Cdr. Ernest Krause: “Needed” isn’t needed. Just “help.” That’s all the Admiralty needs to hear for a modified rendezvous point.
LtCdr. Charlie Cole: The Germans might miss a message as short as that.
It’s a good example on how to write for user interfaces. Consider the context, and remove redundant words.
