Facebook is a social networking site that allows users to connect with others who share the same interests. If you have recently unfriended someone on Facebook, you can try to re-friend them. To do this, you will need their Facebook account information and their email address. You will also need to click on the “Re-friend” button. If the person you want to re-friend is not currently online or has not responded to your messages, it may be because they are busy with other activities or they may be too busy for social media. It is important that you take the time to reach out to them again and make sure that your interactions are positive and supportive.
