Many years ago I was taking an advanced course in programing. I got through the first lesson and left. Back for the second lesson and one lady asked, How do you turn this thing on again. I left. Not as advanced as I thought! I have taught a lot of computer classes, implementing new systems. Some people just should not be allowed near a computer and they were not "old". My family is unhappy with me because I will not join Facebook. Has nothing to do with age, just cautious.
