I'm glad we mostly missed this with Jenny; she didn't get a cell phone until she left for college. All the wonderful times we had driving in the car together would have been spoiled with texting.
Oh, no, cell phones make it much more interesting.
Our daughter really doesn't know how to use a map, although at least the Navy has taught her the basics of how to navigate a ship. All she does when she's ready to go somewhere is hop in the car, turn on the engine, whip out her iPhone, bring up Google Maps, search for her destination, and set the phone on the dashboard cupholder where she can glance down at it.
The other day in Houston she missed a turn to get on the highway enroute a major store by another highway. Google obligingly recalculated the shortest route to get her to our destination. Unfortunately they were all surface streets through some of Houston's more "interesting" residential neighborhoods. Even more annoying was being able to look up and see the highways that we should have taken, with all the cars racing by at 3-4x our speed of advance.
When we're going out to dinner with her friends/roommates, then before she brings up Google Maps she reads her texts. When none of her alleged "friends" have confirmed plans for dinner, she texts them. (Engine still running, but at least we parents are no longer paying for the gas.) Then while she's driving she asks one of us to read the texts to her. Well, actually she asks her mother to read them now, after the unfortunate misinterpretation that occurred when I offered to text one of her friends for her...
Before she had a cell phone, she was only able to tell us stories about these sorts of situations. Now with the cell phone, we can participate in real time. It's the difference between watching a drama from the theater audience versus actually being onstage with the actors!
