to be or not to be, your self that is

The self is such an intricate thing. Amazing how when we are not ourselves we realize this not in accordance with the 'non-self' action being carried out but rather, in hindsight.
Looking back on what we've done we can see that we were not ourselves. At least, our true selves that is.
So what exactly happens to the self when this non-self takes over? has it been abducted? is it taking a break? on sabbatical perhaps? how dare she! the audacity of my true self to take a break when i need her most.
