Yes, if a person says that they are always quiet around new people but feel comfortable talking to their friends who have known them for a long time, it is likely an indication that the person is shy.
Shyness is a personality trait characterized by feelings of social discomfort and a tendency to avoid or be reserved in social interactions, especially with unfamiliar individuals or in new situations. Shy individuals may feel anxious or self-conscious in the presence of strangers, which can make it challenging for them to initiate conversations or express themselves openly.
However, as the person becomes more familiar and comfortable with others, such as their long-term friends, they may feel more relaxed and at ease, making it easier for them to engage in conversation and be themselves.
It's essential to understand that shyness is a normal and common aspect of human behavior. Many people experience varying degrees of shyness in different social situations. While some individuals may naturally be more outgoing and sociable, others may take some time to warm up to new people and environments.
If someone you know is shy, it's essential to be patient and understanding. Give them the space and time they need to feel comfortable, and try to create a supportive and welcoming atmosphere when interacting with them. Over time, as they build trust and familiarity, they may become more open and talkative around you and others.
