I agree with the post in general but I can't say specifically what I really identify with in the post. It was amazing that you mentioned no two people would react the same to some situation. I've often wondered about twins and triplets but even they have different personalities and experiences. [and quadruplets, etc.]
Also I like the comments from others that I've read here. I'm trying to be positive about life and everything going on in it. Sometimes it is hard but I just move on to the next thing I want to try to do.
