Do you know how to make friends with a group of people? Let me tell you the steps about making friends with the group. Maybe it's helpful to you.

First, you need to know what kind of group they are. If people of the group are shy, never ask them "Why don't you talk?" "Why are you quiet?" or "Why do you look shy?" They don't like such questions.

Next, remember that each group is different. They may use different words, like different things or have different ways of "hanging out".

Then, the important thing is that you should try to be outgoing. If you are outgoing, you would become very popular. Remember, nobody wants to make friends with a shy person. 

Finally, find a right topic to talk with the group. For example, you can talk with them about the weather, the latest news, their hobbies or their school life.
