New Thing 92, New Thing Every Day: Send a Text of Only Emoticons

I have received a few of these and have never had any idea what they mean. Also, I did not know that my iPhone had the ability to send a pretty wide range of emoticons, until tonight. It looks like there are maybe more than a hundred.

After some thought, I texted my little sister, Marisa, with just emoticons. They were pleasant -- hearts, smiley faces, etc. I really do not have any clue what it means, if anything, but maybe she does? I have not heard back from her, yet, so we will see what the response is. Hopefully I have not insulted her. I do not think I will be sending any more emoticon texts.
