Don't tell your friends to stop talking to you. Rather, gently explain your reasons for wanting to make this big change. This way, your friends won't feel hurt and they will support you. For example, you could say: "Hey, as a heads up, I'm trying to improve my grade this semester. I won't be able to chat as much during class anymore." If your friends keep talking you and you feel forced to respond, explain that you do not want to get in trouble anymore for talking during class. Make it clear that your studies are important to you, and that you would be happy to talk later. For example, you could say: "I miss joking with you during class too, but I really need to bring my grade up. Why don't we chat after class when we have more time?" If somebody continually disrespects your request, change seats. If you have assigned seating, ask your teacher after class if you can move desks. Tell your teacher that you are becoming distracted in your current spot. Teachers are often willing to move you to a different seat if they know that it will help you focus more in class. If things you would like to say to your friends keep coming up during class, consider writing them down! It can be a fun idea to start an "open journal" with a few of your friends. An open journal is a journal that a few people share and pass between them. This can be a lot of fun, and it also helps you to communicate without breaking the rules in class. Some teachers don't like it when you pass journals back and forth. Make sure that this won't be a distraction to other students, including yourself. If you can't pass the journal back and forth during class, just write your thoughts and comments in the journal, then give it to your friends after class. If you talk a lot because you are angry or upset with others, learn to control how you respond. The next time somebody says something rude, simply stay quiet and nod toward the teacher to indicate that you are trying to pay attention. Raise your hand and speak to the teacher if the other person does not stop. If the situation is delicate and you would prefer not to make a scene, speak to your teacher after class instead. If there's no time after class, visit them during their office hours. If texting, playing games, or checking social media during class is still too tempting, consider turning your phone off. Alternatively, leave it in your locker. Notifications and other audio sounds coming from your cell phone can be a huge distraction to your teacher, classmates, and even yourself.
