Grandmother mentioned wanting to go to the beach, and I asked where. She mentioned a specific area, and I started to map it on the iPhone.
She was transfixed, enthralled, and speechless (but not for long).
Grandmother still insists it can't POSSIBLY be a telephone. No telephone in the world can do what I showed her. She says it's a tiny pocket computer. In a way, I guess she's right. It just happens to make and receive phone calls, too. It also has the word "phone" in its name, but I can't fight her on the "it's not a telephone" thing. I won't win.
