I have been called heartless by my family. This is because they have never seen me crying tears out of joy or regret. When my wife and daughter were moved to tears by a drama, I watched it together with them but had no tears at all. They were shocked that I had no tears. Even at my daughter's wedding, I never had tears of loneliness. Instead, I smiled all the time. However, I have no way to do something with it. Even if I try to force crying, I am unable to have tears. I cannot do anything about it, no matter what anyone says.
I have thought that it was my special nature and that it would be hard to find someone like me. But Yuki Kashiwagi changed my mind and relieved me. I found that she had the same nature as me.
I also tried to find someone who is similar to me on the Internet. Then I found a writer, Maki Funabashi. Like me, she had no tears of joy or regret. But unlike me, she was aggressive and tried to find out why she had no tears out of joy or regret. And she came to see a neuroscientist to find it out. As a result, she found out that people manage to prevent tears out of joy or regret by sending a message to their brains: not to give into emotion. Yuki, Maki and I seem to keep sending the message to our brains. Now that I think about it, I have thought that it is a shame to cry tears. That may have prevented me from having tears out of joy or regret.

　ボクは、「血も涙もない人」と家族に言われてきました。それは、ボクが嬉し涙や悔し涙を流すのを見たことがないからです。娘と妻がドラマをみて号泣している時も、一緒に見ていたのですが、二人にそそられて涙することもありませんでした。二人はボクをみてあきれ返るばかりです。娘の結婚式の時も、寂しさで涙することもありませんでした。でも、こればかりは言われてもどうしようもありません。涙は出そうと思ってもでるものではありません。人になんと言われようが、どうしようもないのです。
　ボクは、これはボク特有の性格で、同じような人を見つけるのは難しいと思っていました。でも、柏木由紀さんクに似ているがわかり、ボクの考えも変わり、安心しました。
　ネットでボクに似た人を検索してみたら、船橋麻貴という作家の方がいらっしゃいました。ボクと同様、船橋さんも、感情で涙がでない人です。でも、彼女はボクと違って、積極的で、涙が出ない理由を探ろうしました。そこで、脳科学者に会いに行ったところ、人は、感情に流されるなと脳に指令を送り続けることで、涙を抑えられることが分かったのです。言われてみると、涙を流すことは恥ずかしいことだと思ってきました。この意識が、涙が抑えているのかもしれません。
