How Fully Homework 2

Source C

With three of our friends I decided to join the London Scottish. My reasons for doing this was that at my age and in my circumstances I would have been ashamed not to do so. My parents would have been ashamed of me if I had not done so. Other reasons were that several of my friends were joining the same regiment. Also I have already decided that I did not want to be a civil engineer. It seemed a dull sort of job.
