Now, all the cat is doing is that it's an infinite loop and it's checking if I am not facing bird, - face bird, and it's -- It's constantly chasing the bird.

猫能做的就是一个死循环,并且它能检测我是不是面对着一只鸟，如果没有就转向那只鸟-,它一直不停地追逐这只鸟。

So in a sense, that's a good infinite loop that is as long as you're using the program, it's constantly checking your grammar and spelling, and underlining things, so infinite loops aren't necessarily bad if the objective is actually being met.

因此从这个意义上说，这是个好的无穷循环,只要你开始使用这个软件，它不停的检查你的语法，拼写或者下划线等，通过这种方式达到目标的时候,这样的无穷循环并不总是坏的。
