Both of my grandmothers do that too. They even Facebook and tweet.

Don't respond to texts she sends you when you're both in the same room. But be aware of the fact that you could get in trouble for that.

parents...

The solution is simple: if she's within talking distance, ignore her texts. Can you customize your phone to not buzz or beep when you receive texts from her? Then delete the texts as soon as you see them so it looks like you never got them. My mom used to tell me to do things while wording the statement as a question, even though it really wasn't. (Ex: Do you want to unload the dishwasher? Do you want to fold my laundry?) I just started walking around with the tail end of my earbuds in my pocket and my earbuds resting on my shoulders. When she asked her 'question', I'd say No, put my earbuds in and leave the room while she was still sputtering. Eventually, she learned to ask questions and state commands. After we remodeled the kitchen, she told me it was my responsibility to keep out cooking utensil drawer organized and orderly. The sad thing was, since my brother moved out, she is the only one who doesn't try to maintain the organization of the notorious drawer. (My dad is neat and cares about it.) There are 4 categories: Grabbers (tongs), Stirrers (egg beaters, mixing sticks), Scoops (ladles and giant spoons), Scrapers (spatulas and pie triangles). She'd toss stuff in there randomly and then yell at/punish me when the drawer wouldn't close or the utensil she was looking for wasn't where it should be. So, over dinner, I announced that, from now on, if I caught her carelessly putting a utensil in the wrong section, I'd put the utensil in her bed. After the second time she rolled over in the middle of the night onto a spatula, she decided that the Kitchen Rules applied to her, too. It takes patience, but it IS possible to teach an old mom new tricks, no matter what bad habits they've picked up in the past.
