Describe the following characters from the story ''The Life You Save May Be Your Own:'' Shiftlet, Lucynell Crater.

Tom T. Shiftlet’s dressing resembles that of a tramp. He has on a “black town suit and a brown felt hat” and carries a tin toolbox. He only has half of his left arm intact. When asked where he hails from, he says, "Tarwater, Tennessee." He claims to be twenty-eight years of age, presently working as a carpenter, and having past experiences as a gospel singer, a railroad foreman, an assistant in an undertaking parlor, a radio studio employee, and a member of the army. According to the old woman, he is a “poor disabled friendless drifting man." His character comes across as untrustworthy, scheming, and selfish. He is as shifty as his name. He works hard to gain the old woman’s trust, then cons her out of her car and just enough money with which he can take off to a place called Mobile. He is willing to go to any lengths to meet his objectives, even marrying the younger Lucynell, who he later abandons at a restaurant called The Hot Spot. He does not care about what will happen to Lucynell, a mentally disabled and mute woman, left all by herself, asleep, in a desolate foreign diner. It is ironic that he is this heartless in spite of posing or acting otherwise.
Lucynell Crater is introduced as an old woman, who goes by the same name as her daughter. She must have lost her teeth due to age, as she declines to take the chewing gum that Shiftlet offers her during their first meeting. She has lived in the lonely house with her mentally handicapped and mute daughter since her husband died. The older Lucynell comes across as selfish and scheming, just like Shiftlet. She plans to coerce Shiftlet into marrying her daughter, in exchange for food and board. She is highly manipulative, as she doesn’t tire of reminding Shiftlet of his destitution and the fact that marrying the younger Lucynell would be a big favor done to him. It is ironic that she claims to love her daughter a lot, yet is desperate to marry her off to a drifter, who does not even appear interested in the girl.
The younger Lucynell is a symbol of innocence. According to The Hot Spot’s counter boy, Lucynell looks like “an angel of Gawd." She is a victim of her mother’s ambition and Shiftlet’s dishonesty.
