This makes sense. It took me a while to figure things out on my phone, and I still can't always remember how to answer a call, because I get them so rarely. If I didn't need a way to call someone to come get me when I'm away from home and exhausted and in pain, I would not have gotten a cell in the first place. My DD gave me the first one, for that very reason. I got forgotten by the Dial-A-Ride once and stood (STOOD! Standing is very painful for more than a few minutes) for over an hour in the snow before a driver stopped to see why I was still there after he'd already passed by me three times.
