Being the provider gives you gray hair and a scowl, sometimes

D. has been torturing himself for the last 5 years, providing for the 6 of us and somehow studying toward a degree or two.
He has a lot more gray hair and a lot more wisdom because of it.
Recently he drove to an interview for a job he really wanted.
Can you just guess what his face looked like, in a tie, in a hot van, with 4 noisy kids, wondering if he could show off his impressive skills enough to be considered for the job?
You dont have to guess, I took a picture.
Lots of eyebrow wrinkles.
Now, can you guess the outcome, from another picture taken later on?

Now our lives change.
Clean, Sell the house, Move.
New Job, New Life.
What a Relief.
Does this mean the gray hairs will turn back to brown?
