When your class is going on a field trip, stand in the middle of the group and wear a lot of cologne/perfume. It's important to try your best to mask your yummy-yummy demigod scent so you don't endanger any of the defenseless mortals in your class. Never separate yourself from the group or you might find yourself monster chow. The older you are, the more important this will be. Especially if your godly parent is very powerful like mine.

Or just don't go.
