Make Things Easy For Them
If you have enough self-confidence and you know that the person you are with hasn’t got the same amount of confidence that you have, be the one to adjust. Not all people who avoid getting into conversations are shy. There are those who avoid eye contact and socializing with people. But just the same, be nice and be the one to reach out to them. Just a smile, an eye contact, or a simple hello might do. That will help you determine who is who.
Help the person feel at ease and persuade him to speak up not by telling him directly but by making him talk more about the topic. If you feel like that person is shy to talk to you but really has thoughts in mind to share, be the one to initiate the conversation. When you have started the conversation, give that person the chance to speak. Like you can ask him questions about your topic or ask what can he say about your opinion.
Think of the situation those shy people are in. Think how hard it is for them to socialize with people. They want to socialize but their shyness prevails. Put yourself in their situation and think of what you can do to make them feel better. Since you are the blessed one who got enough confidence, be kind enough to help others overcome their shyness.
