One other thing about it, if you do have one at home, let me tell you one of the features you may not know: when you fall asleep, it comes alive and it walks around your house and goes through your mail and watches you as you sleep.
另外， 如果你家里拥有一个这个， 让我告诉你一个你也许不知道的作用： 当你熟睡的时候， 它会活过来， 并且在你的房子里走来走去， 并且帮你查看信件， 并且在你睡觉的时候默默的看着你。
