Naturally, you will have your own personal reflection and thoughts on chapter 7, but the following ideas may help you compose your own ideas.
In this chapter, we learn that Harlen and Will first met at Will's mother's funeral. We also learn that Harlen was the one who encouraged Will to move back home and start his own business. At first, Will rejected this idea, but he eventually came around. When Will decided to move back home, he didn't call Harlen; however, when he got off of his flight, Harlen was waiting for him.
Will reflects back on this moment and wonders how long Harlen must have been standing there waiting at the terminal. Although Will sometimes feels like it is hard to be Harlen's friend, he recognizes what a good friend he has been to him. He was there for him when he arrived at the airport. He was there to help him get his business started. He was there for him as his first customer. Again and again, Harlen has gone above and beyond to lend a helping hand to Will.
Learning the history of Will and Harlen's friendship may inspire readers to reflect on their own friendships. Many readers may even have a friendship that mirrors that of Will and Harlen. Additionally, seeing everything Harlen has done to be a good friend may inspire readers to be a better friend themselves.
In this chapter, Will is definitely trying to be the friend that Harlen deserves. When Harlen doesn't show up to a wedding, Will knows something must be wrong, since this is very out of character. When he tries to find out where Harlen is, Bud says that "everybody thought you knew already" since they are such good friends. Perhaps hearing this makes Will feel bad that he didn't know where Harlen was. Whatever the case, Will proves himself to be a good friend when he finds Harlen at home and proceeds to take care of him while he is sick.
Overall, there is much you can learn about friendship in this chapter.
