• Slip it into someone's coat pocket,
• into a friend's locker at school or at the gym
• leave it with the tip for a waitress,
• leave it on the bus.
• pop it into someone's cubby hole at the office,
• stop and leave it in a rural route mailbox,
• add it to the tourist brochure rack on the ferry,
• leave it on the teacher's desk with an apple.

You get the idea!
