"Hey, isn't that too close?"
Hiyori stepped back a bit. When Kaito talked, the distance was always close.
"Oh, is it?" Kaito didn't seem to notice.
Sora was observing. "It's a difference in personal space."
"Personal space?"
"The interpersonal distance each person feels comfortable with. There's great individual variation."
Mira wrote a note. "Edward Hall"
"Yes," Sora acknowledged. "A concept proposed by anthropologist Hall. Classified into four: intimate distance, personal distance, social distance, and public distance."
Kaito showed interest. "How far is that?"
Sora wrote in her notebook. "Intimate distance is 0-45cm. For lovers and family. Personal distance is 45-120cm. Friends and acquaintances. Social distance is 120-360cm. Work relationships. Public distance is over 360cm. Lectures, etc."
"I thought since Hiyori and I are friends, personal distance was fine."
"But your personal distance and my personal distance might be different," Hiyori explained.
Mira nodded. Then wrote. "Cultural differences, personality differences"
"Yes," Sora continued. "Generally, urban people are accustomed to narrow spaces. Rural people prefer wide spaces."
"It also differs by culture," Hiyori added. "Latin cultures have relatively close distance. Nordic cultures have far distance."
Kaito thought. "So what about Japanese people?"
"About medium," Sora answered. "But individual differences are larger."
Mira showed a new note. "Introverted→wide distance, extroverted→narrow distance"
"As a tendency, yes," Hiyori acknowledged. "Introverted people often have wider personal space."
Kaito reflected. "Maybe because I'm extroverted, I tend to get close?"
"That itself isn't bad," Sora said. "But you need to consider the other person's comfort."
Hiyori said gently, "I'm happy you noticed."
Mira wrote. "Distance adjustment = mutual process"
"Exactly," Sora acknowledged. "Distance isn't decided unilaterally, but adjusted by both parties."
Kaito asked. "How do you adjust?"
"Observe the other person's reaction," Hiyori answered. "Stepping back, turning away, avoiding eye contact. These are signs 'too close.'"
"Conversely, approaching, turning toward, maintaining eye contact. These are signs 'closer is okay,'" Sora added.
Kaito wrote in his notebook. "Read nonverbal signs"
Mira added another perspective. "Situation also influences"
"What do you mean?"
Sora explained. "On a crowded train, you can tolerate close distances you normally couldn't. But on an empty train, someone sitting next to you feels unpleasant."
"Context is important."
"Yes. The same distance has different meanings depending on situation."
Hiyori gave an example. "When showing documents at work, getting close is fine, but during small talk, stay a bit apart."
Kaito understood. "It's about TPO."
Mira wrote. "Power relations too"
"Sharp observation," Sora acknowledged. "Bosses can enter subordinates' space easily, but the reverse is difficult."
"Invading personal space can also be an expression of dominance," Hiyori added.
Kaito asked worriedly. "I don't mean to dominate..."
"Even without intent, it can feel that way," Sora explained. "So being conscious is important."
Hiyori proposed an experiment. "Kaito, let's try something."
"What?"
"I'll approach you now. Tell me when it feels uncomfortable."
Hiyori began slowly approaching Kaito.
2 meters, 1.5 meters, 1 meter...
"This far is fine," Kaito said.
80cm, 60cm...
"Ah, maybe a bit close."
Hiyori stopped. "This is the boundary of Kaito's personal distance."
"Interesting. I didn't even notice myself."
Mira was observing. Then wrote. "Changes depending on person"
"Exactly," Sora acknowledged. "You can get close to close people, but keep distance from strangers."
Hiyori summarized. "Distance is a barometer of relationship."
"But also a tool for creating relationships," Sora added. "Maintaining appropriate distance builds trust."
Kaito resolved. "From now on, I'll be conscious of others' comfortable distance."
"Perfect," Hiyori smiled.
Mira showed her final note. "Small considerations, big differences"
The four left the classroom. They walked down the hallway, each maintaining comfortable distance.
"The psychology of distance is profound," Sora said.
"It might be fundamental to human relationships," Hiyori added.
Kaito laughed. "From today, I'll become a distance master."
Mira smiled quietly. Understanding distance is understanding others. From small conflicts, great learning was born.
