There are people whose courage is always on display when they run into fires, protect us, and save us but usually they are trained and ready although that should not diminish our respect for them. We must praise and thank people for their bravery and hope that everyone will step up when called upon. Thanks to coach Andrea Fuentes for what you did and the example you set for everyone.
