Tom Kitten was very fat, and he had grown; several buttons burst off.

小猫汤姆很胖， 而且他长大了； 几个按钮爆裂。

And—soul alive! —that great sigh, which you made me heave, has burst off the very last of them!

而且——灵魂还活着！ ——你让我发出的那一声巨大的叹息， 已经从他们最后的生命中爆发出来了！

It is just so with your buttons: you let them burst off without telling me, and go out with your wristband hanging.

你的纽扣也是如此：你让它们在没有告诉我的情况下爆裂， 然后挂着你的腕带出门。
