I've been texting so long now, I kind of freak out when the phone rings and I get scared of talking to people. 
Yes I feel that way too. I have become too addicted to composing and sending electronic messages.
Do you send emojis too? 
Yup. I find they are very expressive, like happy faces, sad faces.
Do you know how text messages actually work using data?
I just know that they may be sent over a cellular network, or via an Internet connection
Ah okay. I wasn't sure why they were such a big deal when they first came out.
Neither did I, but i soon realized that texting is a quick and easy way to communicate with friends and colleagues.
It sure is. It's nice to be able to communicate subtly without disturbing people around me. 
Exactly, especially where a call would be impolite or inappropriate, like calling very late at night .
