+1 and I'm even older. "growing up" can easily ruin your life: financially devastating, alcoholic, divorce, overweight and early death. That's the story of my Father.
Sorry to hear about your father, that's sad.
My parents divorced when I was 13, that sucked too, and it was a pivotal point in my life, and many of the paths I took were the wrong ones and they came with a heavy price. That might be one of the reasons I fought to keep my marriage together, after 25 years, there were two distinct times I can remember all too well that it nearly ended.
Multiple other times, straws on the camels back, but -
I've seen a lot of people who never "grew up" and for some reason, there is not a lot of appeal in really old kids.
I know one guy, he's got to be over 50, lived in his parents basement until they both died, now no one knows where he ended up as the parents left him nada.
Too many times, alcohol or drugs or work or motorcycles or whatever can be a crutch for those that never "want to grow up" and one day, the crutch breaks.......
Whatever though, I do not want to get into any arguments with anyone about it, that is for sure.
There once was a time that I never trusted anyone over 30, and I knew everything there was to know about anything there was to know anything about.
When you realize how ignorant you were when you thought you were at your peak of brilliance is a humbling experience.
