Thanks, but the difference between tribal medicine man and typical grandmother still leaves room for confusion. A typical grandmother knows that computers exist, but a tribal medicine man might spear me for stealing his soul with this mysterious "light box."

The reason I ask is because I wanted to know if I was supposed to explain the computer to this person or just how it interacts with the internet.

Maybe the question could be "explain the internet to someone from 30 years ago. (Computers present, but no complete internet to speak of)"
