Emojis R US!

I love emojis!

I remember one time writing a Whatsapp message on a friend’s phone and when I clicked on the emojis icon, was shocked to find that he had only 3 or 4 emojis appearing under his frequently used tab. I cannot understand this! How does one express oneself effectively via text if not by the use of emojis?
I can scarce complete a line of text without feeling like it could use a facial expression to go with it, to make it as close as possible to a conversation is my argument. (Also, I just fancy colour and animation.)
