It's usually so much easier to text someone rather than pick up the phone and call.
To your sweetie: "Could you grab some wine on the way home?" It takes a minute when actually dialing and calling might take five, because your spouse things of a hundred other things to tell you while you're on the phone. And hopefully the reply is a simple, "Yep! ;-)"
What about emergencies? Is texting the quickest way to 911?
It may be coming to East Texas.
