Ask if you can leave.

From Create Your Own Story

Most adults would refuse your request; however, this one in particular lacks a spine. He frowned but meekly gave you permission to leave. Although you were courteous, you might regret taking your studies so lightly. And your parents won't be happy that you are skipping another lesson. But, you are still a boy and it is important to enjoy your fleeting youth.

So, now that your day is free how will you spend your time?

Go to the library.

Go to the kitchens.

Go to the training yard.

Go to the throne room.
