I Hate It When Someone Doesnt Text Back

Well, people will be waiting quite a while if they're waiting for me to text them back. I don't text. I don't have a smartphone. Don't want one, although they do have great cameras and the photos look terrific.
I'm one of those people who still has a flip phone. I can receive texts, as I do sometimes from my kids. But sending them, NO. Now I will admit I have sent an OK, a YES, or a time, but a message, NO.
