Well , I wasn't worried when my son

Well , I wasn't worried when my son bought a computer . After all lots of children have parents who don't understand computers . But when my secretary asked me for a computer in office , I really became worried. So i decided to take some lessons in computing and my son became my teacher. He was very helpful. He invited me to sit down in front of the computer screen. I did not know what it was called. When asked him what is was, he said that is was a VDU. I still didn't know what a VDU was, but I was too shy to ask him anymore. From that moment my memory refused to learn because he told me a lot of things that I really didn't understand at all. After a few lessons I began to feel tired. I made an excuse , saying that I had a headache. I suggested we should leave the lesson for another day. Since then I haven't said anything about the computer to my son and my secretary
