People by their very nature are always on the lookout for intruders, trying to prevent those on the outside from getting in. But there will always be those who force their way into our lives, just as there will be those we invite in. But the most troubling of all will be the ones who stand on the outside looking in. The ones we never truly get to know.

人类的天性就是提防那些入侵者，我们努力防止外人进入我们的生活。但就像我们有时会邀请客人一样，总会有人强行进入我们的生活。不过最令人头痛的还是那些站在远处监视着我们的人，我们永远不知道他们的真面目。
