Grassroots football, especially with the younger age groups, is a highly emotive game. It's often the first time children are learning to work as a team and you get to witness them naturally finding their place in that community.
And children are just great. Yes, there may be the occasional bout of frustration or they might suddenly lose the ability to hear instructions, but they will also support each other, check on their teammates and the other side, celebrate like they've won the Cup and reward you with the loveliest smiles.
You get to see, and capture, moments of unbridled joy and growing camaraderie. And the emotions on the sidelines are pretty spectacular too.
