In the beginning, we use Emoji just like anybody else, as an expression in our communication. Then, somehow, there are more Emojis created, from everyday food, transport, activities, etc
As Emojis for everyday topic become more available, we realize we can use more and more Emojis, and the arrangement of Emojis has a meaning.
The problem is, there is no definitive meaning to these group of Emojis. What we have written can have different meaning by someone else. This is not right. It has to have the same meaning (more or less) for all people.
Some people try to translate few articles into Emoji, and its using their own interpretation. The result? not impress us to follow.
