The first reason is Aunt Esther selfishness makes her unhappy but then she starts to change
For example Aunt Esther allows Michael to have a hermit crab and In the beginning Aunt Esther was Yelling at Michael and saying “You hate it here and you hate me.
For another example Michael overheard Aunt Esther talking about him rudely over the phone,This shows that Aunt Esther is Selfish because She doesn’t care about others.
Michael is lonely and wants something or someone to care about him.
For instance Michael buys a
hermit crab because he wanted a companion.
“Michael hadn’t made any friends at his new school and the teachers barely noticed him.”
Michael’s mom and dad died and got a hermit crab,this shows that Michael is lonely.
Sluggo, the hermit crab, is the change Michael and Aunt Esther need.
“Oh what would your mother think,Michael if she could see the mess we’ve gotten ourselves into.”
Another good example is She looked at Michael with a broad smile,but it quickly faded.The boy’s eyes were full of pain.
“Oh my” she whispered “I’m sorry” Aunt Esther hasn’t showed affection to someone in years this shows that Aunt Esther has changed.
Michael and Aunt Esther Lean their heads together and watch sluggo crawl out of his shell this shows that Aunt Esther and Michael have bonded.
In ”Shells” by Cynthia Rylant the two main characters had to have something to change their relationship,Michael and Aunt Esther relationship was distant until sluggo came and brought the two together and changed them.
