What influence does environment have on individuals in any two of these stories: A good man is hard to find The handsomest drowned man in the world Where are you going, where have you been? The lesson Everyday use Things they carried The man to send rain clouds Please provide at least four quotes if possible.

Let's talk about two of these stories: "A Good Man is Hard to Find" by Flannery O'Connor and "Where Are You Going, Where Have You Been?" by Joyce Carol Oates. I'll include two quotes from each, as you requested.
In "A Good Man is Hard to Find," the primary example of environment influencing an individual is the case of the grandmother. (She's not named specifically in the story: she's just called "the grandmother," as she's the mother of the protagonist, Bailey, and the grandmother of his children.) Bailey wants to take the family to Florida for a vacation, but the grandmother wants the group to go to East Tennessee, where she is from, instead. Her grandchildren have never been there, she argues, and they don't understand her background.
Here, right off the bat, and throughout the story, she tells (and shows) us about what it means to be from East Tennessee. Outward appearance and propriety are important, apparently:

The old lady settled herself comfortably, removing her white cotton gloves and putting them up with her purse on the shelf in front of the back window. The children's mother still had on slacks and still had her head tied up in a green kerchief, but the grandmother had on a navy blue straw sailor hat with a bunch of white violets on the brim and a navy blue dress with a small white dot in the print. Her collars and cuffs were white organdy trimmed with lace and at her neckline she had pinned a purple spray of cloth violets containing a sachet. In case of an accident, anyone seeing her dead on the highway would know at once that she was a lady.

The grandmother's language and behavior show that she's not worried about fitting in with her son or grandchildren. It's important to her to show them the old-world etiquette that was commonplace in her era. Her vocabulary includes terms and phrases that would be considered politically incorrect, if not downright inflammatory, if used today. (I won't quote these here, but you can spot them quickly in the story.) The passage below shows how her upbringing has shaped her worldview:

"In my time," said the grandmother, folding her thin veined fingers, "children were more respectful of their native states and their parents and everything else. People did right then. Oh look at the cute little pickaninny!" she said and pointed to a Negro child standing in the door of a shack. 

Moving onto "Where Are You Going, Where Have You Been?" The central character is Connie, a 15-year-old girl who rebels against her family and their expectations for her, and ends up getting herself into serious trouble because of it.
Even though Connie doesn't want to have much to do with the environment she was raised in, she can't help but be a product of it. Here, she expresses her distaste for the conventional family activities she's expected to take part in: 

Her parents and sister were going to a barbecue at an aunt's house and Connie said no, she wasn't interested, rolling her eyes to let her mother know just what she thought of it. "Stay home alone then," her mother said sharply. Connie sat out back in a lawn chair and watched them drive away, her father quiet and bald, hunched around so that he could back the car out, her mother with a look that was still angry and not at all softened through the windshield, and in the back seat poor old June, all dressed up as if she didn't know what a barbecue was, with all the running yelling kids and the flies.

Connie resents her parents and her dutiful (and in Connie's mind, boring) older sister. But later, when she's in a terrifying situation with Arnold Friend, an older man who's forcing himself onto her, she clings to the norms of the family and culture she's familiar with. Arnold speaks first, and Connie responds:

"I'll tell you how it is, I'm always nice at first, the first time. I'll hold you so tight you won't think you have to try to get away or pretend anything because you'll know you can't. And I'll come inside you where it's all secret and you'll give in to me and you'll love me."
"Shut up! You're crazy!" Connie said. She backed away from the door. She put her hands up against her ears as if she'd heard something terrible, something not meant for her. "People don't talk like that, you're crazy," she muttered. Her heart was almost too big now for her chest and its pumping made sweat break out all over her.

This passage makes it clear that Connie is, indeed, influenced by her environment, even though she might not accept it or want it. When she finds herself in an unsafe situation, she wants to return to a familiar setting and the socially acceptable forms of behavior that she learned from her parents.
