Since the beginning of smartphones, Emojis have become a global language for all users. The reason why sending an Emoji instead of words is better, technically, is because they save a lot of time and express the real feelings behind each sentence, even the untold words.
In fact, some researchers admit that Emojis are very beneficial when it comes to building relationships. I bet you have the same question as I did when I first heard that, too. How can that be possible?
Sending an Emoji whose eyes are closed because it is laughing too hard that it started crying is not actually the same thing as writing a heartfelt text to your loved one, or even looking them in their eyes as you speak to them, right?
