Okay kiddo, so imagine that your house is a big coloring book that needs to be painted. A house painter is like the person who colors all over the book to make it look nice and pretty. They use a special paintbrush and paint to cover every part of the walls, ceilings, and sometimes even the outside of the house.
Now, a decorator is like the person who helps decide what colors and designs to use when painting. They might look at different colors and patterns and suggest what would look best in your house. They also decide on things like the color of the furniture, curtains, and other decorations that will match the painted walls.
So, the painter and decorator work together to make your house look awesome! The painter colors the walls and the decorator decides what kind of colors and patterns would be the best to make it look amazing.
