Why do you say that tears are the most worthless thing?

Because people who really love you won't make you cry, they are reluctant to part with it and will feel distressed, so tears are unnecessary; People who don't love you don't care about your tears at all, so tears are useless; Since no matter what, tears are unnecessary, then natural tears are the most worthless things! But I think it's good for eye health to shed some tears properly, hehe!
