I do, of course. But only in certain ways. I was a very happy, if disturbed, 8 year old. Some things were definitely better then, and in lots of other times too. Some things are definitely better now.
It won't always be like that, but at least it's not completely predictable.
I think every generation feels that way as they get older. You always miss what was familiar to you when you were younger. I am unapologetically nostalgic.
