Mistaken Identity

Is it too late to declare that I have made an unfortunate mistake? Is it too late to confess my erroneous miscalculation? I took you for a father, a friend, a brother, a mentor not knowing that YOU were only an impostor. Pretending to care when I was in despair, Pretending to celebrate when I was elated, Pretending to mourn when I wore a frown. Pretending, Pretending, always pretending. So, answer this crucial question- is it too late to declare that I have made an unfortunate or rather grave mistake?
