Oh, well my point is Role Playing is about playing the role...acting...as a fictional character. Quite often the character can do things the player can't.
But the player is the one in control. The character might be a 41 year old trench veteran from the Second Inhuman War: but the player is a 22 year old that works at Circle K. So when the character acts, it's the player that is in the driver seat.
Now the player can choose to act like a "41 year old trench veteran from the Second Inhuman War", or they can "act like themselves".
