unforgiving 可以想成一扇「錯一次就關上、而且不會再打開」的門。犯的錯也許很小，也許是很久以前的事，但那扇門就是不鬆手。把門關住的可以是一個人，也可以是一片沙漠、一份行程表。畫面都一樣：它不放過你，也不給第二次機會。From the word’s history
At the level of its parts the word is simply un- plus forgiving, the -ing form of forgive, so its literal value is not forgiving.
從構詞看，這個字就是 un-（不）加上 forgiving（會原諒的），而 forgiving 來自 forgive。字面價值就是「不原諒」，其他用法都可以掛在這個字面意思上理解。

不留餘地的環境與條件
同一扇門被搬到沒有生命的東西上。沙漠不會生氣，行程表也沒有心情，但它們一樣「錯一次就關上」。
