What do you think this way of talking? Is clicking tongue not so bad manners? Please take a look at this video. It was at 0:50. "It's ... (here) it's beautiful" I'm glad if you give me your opinion. https://youtu.be/wVBJJySWfoA?t=45s I sometimes see native English speakers clicking their tongue in conversation like this video. If someone does this during talking with me, I tend to focus on their way of speaking more than topics. It's not only me feeling that because I found out that many Japanese people asked the same question on a Japanese website, but answers were only from Japanese so it still remains a matter of speculation. I guess the Japanese way of using tongue is quite different from English one so I don't see Japanese people do that. In Japan, it's considered bad manners so I hope Japanese learners know this.
