A future driving instructor

I"m a teacher in a primary school. My students are kids aged 6 to 10 and my job is to make sure they get to know the basics of maths and learn to read and write properly by the time they finish Year 6. Once we were talking about jobs. The kids gave examples of various professions, some of them really unusual, to my surprise. They also had to think of what they would like to do when they grow up. Well, there were future business people, investors, teachers, actors, singers, zoo keepers and doctors. One boy wanted to be a driving instructor. I asked him what a driving instructor should be like. He didn"t really know what to say, but their kids helped him. Some comments were: nice, just, punctual, brave (because it"s dangerous to travel in a car with somebody unskilled behind the wheel), and he or she must be a perfect driver. I asked the boy why he would like to be a driving instructor. He said it as only because a driving instructor can earn a lot of money. I didn"t know what to say because it was a bit funny, and at the same time I was curious if the job seemed really interesting to him in any way. I asked him that question, ad he said it was quite interesting, but sometimes it can be boring as well. Especially when you have to go around the town several times during the day.
