All about harmonisation
When the same things are at big and littles house it is easy. The big can be at the little's house and find just what he needs, and the little can be at the bigs house and find just what needs.
But sometimes there are things that are at one of the bear's houses but not at the other. Oh dear! Imagine what it is like when a bear goes to do a job or something but finds that the thing that they need is at the wrong house! It can make a bear a very grumpy animal (and that is not nice).
So the little bear invented harmonisation. Harmonisation means that there are the same things at both houses so that there is no problems.
Things that have been harmonised are: soap, toothpase, toothbrushes, pants, griddle pans, rice cookers. Lots of ingredients are harmonised. It can get all rather complicated makings sure everything is in the right place. You can imagine what it is like when a bear comes home to cook some rice but dosen't have a rice cooker can't you. Deary me!
But the bears are getting good at harmonisation so that everything is easy, and the bears don't have to worry about where they are at all.
Big bear is a little bit worried about what will happen when the bears have one house to all the ingredients and the rice cookers and things. But then, that can be a worry for another day.
