In To Kill a Mockingbird, explain Scout's statement that "she (Mayella) was even lonelier than Boo Radley."

Boo and Mayella may well have been the two loneliest
people in Maycomb, but Mayella took even more extreme measures than Boo to make friends.
Whether Boo knew about his reputation as Maycomb's leading ghoul, his reclusive position
in his house was at least voluntary; he could have chosen to venture out into the
neighborhood had he wanted. He would have been welcomed by Atticus and Miss Maudie, and
the children would probably have learned to accept him--as Scout did in the final
chapter. Mayella, however, had little choice in the matter. She was stuck at her home on
the edge of town, responsible for taking care of her younger siblings. She had no
friends of her own, no money, and no one visited her despised family. Few people passed
her way accept for Tom Robinson--a married African-American man. Although the Ewells
apparently despised their Negro neighbors, Tom appeared to be her only choice for
companionship. So, when he entered her home, she took a chance on one of the least
likely persons imaginable to be interested in her advances.
