Let me present my case, step by step.
Let us begin back in the days of yore circa 1988, before L and I had the Son. Here we are with my brother's two oldest kids:
Then a few years later the Son was born and not much had changed:
About a year later and look at how the gray side-burns were coming forth:
Add another year or so and look at the gray as we played on the floor at mom and dad's:
Add another bit and see how the hair on top is turning gray and starting to thin:
From there on out it just seems to go faster and faster. Here we all are a few years later:
By the time 2000 rolled around, we were still up for a good dress up occasion, but the white was running rampant:
Of course, the teen age years were yet to come, and with them came still more white (and the Son got a lot taller!):
In the same time frame, here is a better view of the gray taking over. (And no, I don't know why the Son is pointing at the ceiling.)
I'll leave you with this shot of me in my office a few years ago. The thing I am holding is an original art creation sold to benefit the local historical society - I called it "Thing-a-ma-boob".
(I'm kidding of course - the Son had little to do with the changes in my hair.)
