公關（這份工作）
核心畫面
One way to hold it: an organization has a front door. Inside, people make things and make decisions. Outside stand customers, neighbours, reporters, everyone else.

可以想成一個組織有一道大門。門裡面的人做事、做決定；門外面站著顧客、鄰居、記者，還有所有其他人。public relations 就活在這道門上。有時候它指「站在門口向外說明」的那份工作，有時候它指門裡門外之間那層關係本身。From the word’s history
The phrase dates from the early twentieth century, and Wiktionary notes it spread as a neutral replacement for propaganda once that word turned negative — which fits the door image: the same explaining work, renamed as a relationship rather than a message pushed out.
根據 Wiktionary，這個說法出現在二十世紀初，並且是在 propaganda（宣傳）變得負面之後，被當成中性的替代說法而流行起來。這條線索剛好對上門口的畫面：同樣是向外說明，但重點被改寫成「關係」，而不是單向推出去的訊息。
