-Piracy is typically an act of robbery or criminal violence at sea. The term can include acts committed on land, in the air, or in other major bodies of water or on a shore. It does not normally include crimes committed against persons traveling on the same vessel as the perpetrator (e.g. one passenger stealing from others on the same vessel). The term has been used throughout history to refer to raids across land borders by non-state agents.

-What is it with that Mary girl?  Dragging me to school every day. As if I had a choice.  What you don't hear in those nursery rhymes is that she starves me if I don't go to school with her; it's the only way I can stay alive!  I'm thinking about being adopted by Little Bo Peep, sure I may get lost, but anything is better than being with Mary and those little brats at school (shudder, shudder).
