Firefighter

Neo - "I want to be a fireman when I grow up"
Mummy - "That would be a scary job, you would have to go into burning buildings"
Neo - "No to one which goes in buildings, a helicopter fireman"
Mummy - "Oh the ones who fly over fires and unload all of the water on top of the fires?"
Neo - "Yeah one of them"
Mummy - "Well that's still a dangerous job as you can't fly to close to the fires otherwise your helicopter might catch on fire"
Neo - "Mine won't as it will made of special stuff which can't catch on fire"
