n.小心；仔細(xì)；慎重

He slowly opened the package with carefulness. 他慢慢地小心地打開包裝。

Was it because of the influence of the mild low tune of the beginning paragraph, or the carefulness considering that I couldn't dance, or the carefulness of his own? 不知是受了開始那段輕柔低調(diào)的感染，還是他考慮到我不會跳而采取的小心，或者是他自己也有些拘謹(jǐn)？
