What if the 'someone' is yourself?
I think the same applies. That's what I'm saying. Our forgiveness is not perfect, because we still remember. Plus, we always have Satan there to remind us as well. It is at those times that we have to remind ourselves to not hold on to that which God has already forgiven. We are not greater than He is. If He says that He will not hold it to our charge, who are we to do otherwise?
