It's pretty well known that "girls mature faster than boys." Thing is, I don't think the difference in rate changes over the course of life.
I've told Tamar that her expectations of me, while valid and certainly worthy of reaching, are aggressive in terms of timeframe.
Wives are like casks in whose care their husbands take time to mature, like a good scotch.
By my estimates, it'll be at least another 18 years before I'm at the maturity level she expects :-)
A distiller will tell you...you need some patience.
