Events

In high-level programming, an event is a mechanism by which external influence triggers an internal response.

In life — it is an encounter, a loss, inspiration, trauma, love — arriving off-schedule.

public class Human : BaseEntity
{
    public event Action? OnLoss;
    public event Action? OnLove;
    public event Action? OnAwakening;

    public void Experience(string eventType)
    {
        switch (eventType)
        {
            case "loss": OnLoss?.Invoke(); break;
            case "love": OnLove?.Invoke(); break;
            case "awakening": OnAwakening?.Invoke(); break;
        }
    }
}

An event is not a method you call yourself.
It is an external signal — to which you either respond, or ignore.
But you can no longer remain as you were.

If override is active code change, then event is an external trigger activating latent behavior.

public class Adult : Human
{
    public Adult()
    {
        OnLoss += () => Console.WriteLine("Grief reshapes my values.");
        OnLove += () => Console.WriteLine("Connection expands my world.");
        OnAwakening += () => Console.WriteLine("Old code deprecated. New logic compiling...");
    }
}

At first, you are just Human — unsubscribed to anything.
But with time and experience, you subscribe (+=) to various events.

We do not choose what happens to us.
But we choose how to respond.
event is life happening.
handler is your inner readiness to answer.
