There are a few things you can do to make sure your Facebook friendship is as strong as it could be. First, make sure you’re both on the same page. This will help keep in touch and make sure you have the same interests. Next, try to stay away from any flame wars or arguments. These can quickly turn into arguments that you’ll never be able to win. Finally, try to show your friend that you care about them by sending them messages and posts that show how much you appreciate them.
