It does make you proud when you see your kid's hard work payoff. As a parent involved with your kid's activities only you really know how much they put into it.
I was, and still am, proud of my DS's work ethic while he was on the varisty football, weight lifting and academic teams.
In football they reached the semi-finals his junior and senior year (years he was a starter, OG & DE) with a final 12-2 record each year.
He came in 3rd in his weight class at the state championships his senior year of weight lifting.
The school's academic team came in 3rd in the state (all class sizes) and the team received an invitation to the national championships for the first time ever his senior year. He was captain of the team.
His senior year he came in 4th in Physics and 5th in Chemistry in the state's academic championships, all classes. He won the state championship in General Science his sophomore year.
Congrats to your kids for their accomplishments.
