Parents and smart phones. Something's not quite right. I say: Bring a little nostalgia into the picture!!
eBay: search for "retro handset smartphone". Now she can put the dumb phone in her purse and talk like a NORMAL PERSON on her headset. (She had been getting a little too "Real Housewives" for my taste...always putting people on speaker and holding the phone in front of her mouth.)
p.s. Extra favorite daughter points for matching the headset to the phone.
