This one hits me real hard every time I view it.
It's a combination of childhood nostalgia and dreams that I wish and hope to be fulfilled. I'll be making the military my lifetime career, but there is still a big part of me that wants to have a son of my own to mentor to be a great man, better than me, or a daughter that can be very respectable and pure.
Not only that but it reminds me of how precious kids are, how they need to be protected and nurtured to have a fun childhood but also gain basic knowledge and life skills to be thrown into the cruel world we live in, and thinking about how many government's and sick organizations want to pervert children's youth and sign them to debauchery towards pedophile and lgbt sickness. We have to protect our young as much as possible, they're innocence must be protected. They are our future.
