I've never explicitly retired a character in any sense. Anytime I've stopped playing a character who I really got into RP with, it's because I've had to abandon them due to anxiety. At that point, I can't even talk to anyone, so there's no way of getting any closure.
Not sure I have any relevant point, just had to get it off my chest.
