If someone uses a lot of smiley faces when they text you...?

I personally only use them with good friends because I know there are people who read into them too much. Some people do use it as a flirting technique but some people like me just use them to add a little something to the message

Context is paramount.

The words surrounding the emoticon are important.

Note the following:

I like you. (Smiley face)

I want to spend all my life and available resources attempting to kill you. (Smiley face.)

I use them a lot, doesn't always mean I like someone. It just shows that you're sending them a friendly message and you're enjoying the conversation. Or it might just be out of habit...

Um.......i dont text so i dont know really. I guess they like you?
