It's not uncommon for people to behave differently in different social settings, and your best friend's behavior is an example of that. There could be various reasons behind this change in her behavior when she's with her friends versus when it's just the two of you. Here are some potential factors to consider:
Comfort level: Your best friend might feel more comfortable and at ease when surrounded by her friends, which could lead to her being more talkative and open in those situations.
Social dynamics: Different social groups can have unique dynamics. Your best friend's behavior could be influenced by the dynamics within her friend group, and she might be adapting to fit in or feel more accepted.
Shared interests: With her friends, she might be engaging in activities or conversations centered around shared interests, making it easier for her to be more talkative. When it's just the two of you, the topics of conversation might differ, and she might be less inclined to initiate discussions.
Personal differences: People have varying levels of comfort when it comes to one-on-one interactions compared to group settings. Some individuals thrive in group environments, while others feel more at ease in one-on-one settings.
Communication style: Your best friend's communication style may be different with different people. Some individuals naturally talk more or less depending on the individuals they are interacting with.
What you can do:
Open communication: If you feel comfortable, have an open and honest conversation with your best friend about your observations. Approach the topic with curiosity and without judgment, expressing that you've noticed a difference in her behavior and that you're interested in understanding why.
Be understanding: Remember that people are multifaceted and can behave differently in various situations. Be understanding and accepting of your best friend's behavior without taking it personally.
Create a safe space: Ensure that when you two are together, she feels comfortable expressing herself. Be an active listener and show genuine interest in her thoughts and feelings.
Plan activities she enjoys: Engage in activities that your best friend enjoys or topics that she's passionate about. This can help her feel more comfortable and engaged in the conversation.
Give her space: If she seems quieter when it's just the two of you, respect her space and don't push her to talk if she doesn't feel like it. Sometimes people just need time to be comfortable and open up.
Encourage group outings: Consider spending time with her and her friends together occasionally. This way, you can experience her more talkative side while still maintaining your one-on-one friendship.
Remember that people's behavior can be influenced by various factors, and it's essential to be patient and understanding with your best friend. Keep fostering your friendship, and over time, she might become more comfortable being open and talkative with you in all settings.
