In Selma Lagerlöf's "The Peddler," the crofter's talkative and friendly nature towards the peddler stems primarily from his loneliness and desire for companionship.

• Loneliness: The crofter lives an isolated life in his cottage. He is old and lives alone, with little to no company. The arrival of the peddler breaks the monotony and provides a welcome opportunity for conversation.
• Desire for Connection: The crofter is eager to share his stories and experiences with someone who will listen. He craves human connection and finds it in the peddler's presence, even if the peddler is a stranger.
• Generosity and Hospitality: The crofter is naturally generous and hospitable. He welcomes the peddler into his home, offers him food and shelter, and treats him with kindness, reflecting his inherent desire to help others and be a good host.

Ultimately, the crofter's talkativeness and friendliness are a direct result of his need for companionship and his generous nature, making him open and welcoming to the peddler despite his unfamiliarity.
