Annabeth made sure her kids knew how to use the fire extinguisher. Leo came over to the Jacksons' house often to babysit, and that normally ended with something on fire. Of course, they could just use their water powers, but those attracted monsters. So the two of them were stuck with regular fire extinguishers.
"Mom!" Her six year old daughter wailed "Uncle Leo set the couch on fire!"
"I'll be there in a second!" Annabeth shouted back. Just because her kids knew how to use a fire extinguisher, didn't mean they liked using them.
When she reached the living room, Annabeth was surprised the fire department hadn't been called. The couch was a fireball. She sprayed it with the white foam, and waited for the smoke to clear.
"Leo Valdez, get your lazy butt in here!"
