Inigo decided a while ago that when he goes to university, he will study music, so he can be a singer.
Today, after I explained what the army is, and why they exist, he found out how comes the world is. I explained that there are people who think about complex problems all the time, who try to work out right from wrong, and who try to define grey areas.
He has changed his plan. Now, he wants to study music, and philosophy.
