The literary device used to describe Johnny's mugging is idiom
The attitude of the author
Answer:
I agree with the statement "In order to have good friends, you have to be a good friend", because if I want respect and kindness from someone, I assume that person would want respect and kindness from me. You have to treat people, how you would want to be treated, so if you want to have a good friend, you need to expect that they want the same. Being good towards others, and giving them respect, makes other people respect you, and be kind towards you. This saying reminds of another quote "Don't give an inch and expect a mile."
