I never used to text when I was in elementary school, but once I got into middle school it was how everyone communicated. When we were in elementary, it was so cool to get a call from your friend, but now it is lame.
It makes sense why texting is more popular now a days. First people are always busy and don't have enough time to have a conversation out loud and second with new phones coming out it just makes texting easier. If you are in school you can't just go to your locker and call your mom that you need something, you text her and she will get it faster.
