He was such a good dog, though, and I hate to see him rot away. But I'm also tired of carrying him around with me in a sack, lugging him into the freezer morning and night.

他是一条那么好的狗，我不愿看着他就这么烂掉，但我也厌倦了把他装进麻袋随身带着，每天早晚还要把袋子搬进冰箱里。

Maybe my heart is getting old and weak, or maybe I'm just dog-tired.

也许我的心脏年纪大了，开始衰弱；又或者我实在是太累了。
