Imagine the following situation.
My friend bought a new mobile phone. It has many functions, and he paid it a lot.
The only bad thing is that the instructions is in English, and he does not know English language.
And so it’s been a few months from when my friend bought this phone… and I note that my friend does not send messages with his new phone, but when someone sends him a message (SMS), he call that person immediately.
I asked him why not he send a message back. He said to me that he do not know how to handle any function on his mobile phone! I asked him: “so why not you see how it goes, push buttons, in the end you will learn?”
