可以想成這樣一個畫面：事情在那邊發生，卻始終碰不到你。那件事跟你之間沒有接上線，所以你的心不會揪起來，也不會被拉過去。少掉的是哪一條線，就決定了是哪一種用法：少了「擔心」那條線，就是不緊張；少了「在意」那條線，就是沒興趣。From the word’s history
Wiktionary analyses the word as un- + concerned, or unconcern + -ed. The un- is simply the switch that turns concerned off, which is why both uses are read against what concerned would have meant.
資料把這個字拆成 un- 加 concerned，或 unconcern 加 -ed。un- 就是把 concerned 關掉的開關。所以兩種用法都要對照 concerned 來理解：一邊關掉「擔心」，一邊關掉「有關、在意」。
