If you meet someone for the first time in person, they just look like what you see, but everything is very different online. Yesterday, when I watched some videos on social media, I was attracted to a woman who looked a little bit like one of my best friends, but the slight figure definitely didn't belong to my friend. Just as I was going to swipe away, I suddenly found the account name was as the same as my friends' account name on another social media app. I understood that it was definitely my friend. I saw many people gave her great comments about her beauty below. As for me, I was not supposed to leave anything below. This thing tells me what my friend really wanted us to think about her. Obviously it's not what we see in person. Social media apps have very strong functions which can easily modify a person's pictures to look prefect without doing anything. This reminds me of the software we used many years ago called PS. So, the world has been changing from that moment . What shoud we do to keep our interpersonal relationships?
