Sometimes I dream about my own three house. It wil be localized in the forest near my house. It will structured wooden. I hope that my brother will help me do it. When three house will be ready I will start organize inside. On the walls will be many posters my best actors and singers. On the centre will stay table and four chairs, Under furnitures will be coloured carpet. At the wall will stay cabinet with books. Next to cabinet will stay bed. On the bed will sit my favourite mascots. I think that this three house will be comfortable and attractive. It will be my ideal three house.
