An emoji which is showing one's emotions through symbols,signs and objects without writing out the word of how one's feels which is mostly with smartphone while chatting on different chatting platforms and other sites too is really rewarding. I like using emoji especially when I'm in no mood to type long words or sentences or I don't want to type statements that I will be be misquoted out of context. Emoji sometimes does a better job of presenting an angry thing in a very mild way.
So it's good thing to use emoji which I do alot so as to add clarity to my words in case I couldn't communicate properly with my words and where words fail then the symbols of emoji can help out.
It even help to beautify our conversation on social media like Instagram.
