Do you have many friends?Making friends is a skill like most skills.It improves with practice.If you want to meet people and make friends with them, you must be willing to take some action .You won,t make friends staying at home alone .Join a club or a group .Taking with those who like the same things as you di is much easier.
Many people are nervous when talking to new people ,so you should try to act self-confident ,you should act more confident when you talking to new people , then you will feel more comfortable.
Please remember don't wait for the other person to start a conversation,you should take more action.
