When my wife and I were shopping for a new (used) car a few years ago, we had a list of “must-haves.” We need a car that I (being 6' 4") could fit in, but one that wasn't too big for my wife (who is 5' 1"). Of course, a roomy backseat was needed (as we wanted to start a family), as well as a large trunk for storage. We reviewed many different cars, and, with this list of qualities in mind, found a car that we’ve had ever since.
After my mom got her first cell phone, it took her a good six months to learn to check her voicemail. We’d show her, and she’d be able to check it that day. Two days later, she'd call me asking how to check her voicemail. We had to write down instructions on what buttons to press and reminders of her voicemail box password.
