My only use for a "mobile" phone is my requirement that when "we" go shopping we both must carry our exceedingly basic phones. She frequently resists, so stern insistence is necessary.

This is because "she of short attention span" also is somewhat short in stature and is able to instantly disappear in most shops.

Due to her limited mobility, she almost always grabs one of the stores' "scooters" so she can disappear with extreme rapidity. Sitting on the scooter makes her even more "invisible" from an adjacent aisle. (I've sometimes had to listen for the "warning beeper" when she decides to back up on the scooter, as the only means of detecting her location. Fortunately she's sometimes a bit unaware of which direction she's going(?).)

Due to my limited ability to walk long distances rapidly (up one aisle and down the next ad infinitum) she can stay "disappeared" almost indefinitely (at least until the scooter battery dies).

I've considered a leash, but she manages to snake out of the harness faster than one of our cats, and that most likely would end up with me dragging in the dust behind her scooter should I happen to find an inescapable harness.

Although in very rare circumstances while "out alone" I might "call home" with a question about what she might want, this invariably leads to a separate store (or four or five) in different parts of town (the town is about 20 miles wide, and of course you must get the quilting accessories before you get the ice cream if you want to get both home safely, which may mean crossing town multiple times). It's quicker to go home and ask her there.

(Of course I'm only joking a bit here ...)

OUCH!
