using little pictures in texts

There is a hidden keyboard on iPhones that is full of funny faces and little pictures.  It is called the emoji keyboard and the pictures range from a chicken to a piece of sushi, to a sunset and an American flag.  I go through stages of using it.  Some days, I use a picture in every text I send.  Other times I go weeks without using one.  I am on a picture kick again and realized the other day that I send some ridiculous messages to my friends and family, just so I can use them.  It is colorful, fun, and I love adding them, but sometimes I don’t really end up saying what I want to say.  They also don't work on non-iPhone phones, which is a total bummer. 

To install the emoji keyboard, follow this path: Settings > General > Keyboard > International Keyboards > Add New Keyboard > Emoji
