Please note! Blocking a person does not block them from sending you PlayStation®Network messages. If you no longer want to receive PlayStation®Network messages from a person, go to the PlayStation®3 XMB™ menu or PlayStation®Vita home screen. See PlayStation®3 or PS Vita User's Guide for details.
"The emptiness of the heart you chose. The pain you suffer while trying to save them. The hatred you feel when you just have been lied to. The sorrow you feel for hurting the one you love. To hate, you must feel love. To love, you must feel pain. To feel pain, you must feel sorrow. To feel sorrow you must feel loss. To feel loss, you must feel you. You are the key to your emotions. Only you should control them. Don't let people take them over. Control them and keep them as your own." - Alyssa Jaeger
