An arrogant person considers himself perfect. This is the chief harm of arrogance. It interferes with a person's main task in life—becoming a better person.
It's funny, because my last record was a lot about isolation and people living in separate worlds that other people can't even understand, which drug addiction is the perfect negative example of.
When you look back on your life, it looks as though it were a plot, but when you are into it, it's a mess: just one surprise after another. Then, later, you see it was perfect.
I have stated it plain, an' my argument's thus ( It's all one, says the Sapper) There's only one Corps which is perfect - that's us; An' they call us Her Majesty's Engineers, With the rank and pay of a Sapper!
