The apartment is tiny so he keeps the dog's bed tucked away all day until he brings it out at night.公寓房间很小，他只好白天将狗窝收起，晚上再拿出来。Thanks to them, I can walk out of the house without having to stop the milk, put the animals in kennels, or make sure everything is locked.有了它们，我出门前不必再取消送奶，把狗关进狗窝，或是确认所有的东西都锁上了。
