Strangely enough, when you get older the things you didn't understand when you were a child start to make sense. When this happened, I should have done that. When that happened, I should have said this. those types of things. You start to understand rather than regret. It may be closer to repentance. So it may be that I do want to repent and erase the ignorant self from my childhood.
