Dialogue:"the most important thing in the world is finding people you can trust with your life. I'll tell you how to easily add friends: Use the Friends List.
Press the Alt key to bring up the UI menu and then take a look at the Social menu. Can you see the Friends option? Click on that to open the Friends List, click Add Friend, and simply enter the name of the character you wish to add. If there are too many, press the Alt key and right-click on the character you wish to add and choose Add as Friend. Easy, right?"
