I just googled and got emoji keyboard set up on my iphone. It was so easy and quite entertaining and bonding for DH and I. So I am sure to be annoying by throwing emoji into my work group texts and all. How come I just found out about this now?! Tell me I am not the last one to do this or the only one using them. Also if you don't have an iphone can you still see them?
Eta: for those of you who want to expand your playful expression go to Settings-General-Keyboard-Keyboards. Add emoji and click the globe the next time your keyboard comes up.
