//1. The EventHandler delegate that eventually stores a reference of our handling method
//2. The OnEvent virtual which then checks to see if the delegate has a valid reference, if it does, then it calls this method
//I then create the handlers outside the context of the class, passing in a context reference "object sender"
//where sender is the object that raises the event, in this case some instance of Foody
