@mumairali,
Ok, here goes.
My proposed field of study is to be an engineer. Why you may ask? Well, because I really really like trains. I already have a hat, which was part of the set I received one Christmas. I wear it all the time.
My specific concentration areas of interest would be learning how to toot the horn, and gaging when to slow down to a 1/4 of a mile an hour crawl when the last 3 cars behind my engine are just traveling over a road intersection.
