My husband is happy that I'm finally acting older than 25! When I was 30, he said my maturity level was maybe--maybe--18. When I hit 40, he said I was closer to 25.
Now, in many ways I'm acting closer to 30...but at some point, ones cares less what others think. Add that to my natural obliviousness and I'm likely regressing a bit. I do think more, though. When I have to. Which I try to avoid.
