And most people do boot have the skill to do a full character model at the age of 6. It takes special talent nature to do that even when old. That is even ignoring the fact that people change and adapt over time in hard to predict ways.
So this thought exercise is actually protecting your own wishes through the light of some imagined model of a person. Might as well use Tarot cards instead.
The poster said he was 6 in 2001. It's no longer 2001, and he's no longer 6. I told him he couldn't have done it back then but it might be worth trying now.
I think what GP is aiming at is this: If you think you are a worse person (whatever that means) than you could be, be it from your or any other persons' perspective, is it too late to change?
Or put differently: Years after someones death, the picture of what one could be, is a mind-game already. From here to picturing what you/your mind would like to change is not that much of a stretch.
I'm a father, and I used to worry about what might happen to my young kids if I died. It would be a great comfort to me to imagine them, after they got older, making an effort to interview people who knew me, asking about what I was interested in, what mattered to me, what I used to talk about, how I talked, how serious/happy/neurotic/patient/stingy/grouchy/etc. I was. With this model, they could imagine conversations with me, discuss things with me, try not to disappoint me, etc.
Fortunately--for me, anyway--my kids are old enough now that they will never get my voice out of their heads, even if I get hit by a bus tomorrow (and even if they are driving the bus!) It's too late for them.
How about you? If you seriously think she might have made you a better person, why not help her by giving her a second chance?
