We just moved an electronic piano from my older daughter's room to the living room.
The piano had been moved two and a half years ago once for some reasons. See the entry before [E:note]
During these years, they sometimes good relations sharing the room when the other one was playing the piano.
But during the test period of the older one, she was sometimes nervous even when younger one played it with headphones.
I wanted them to share nicely as the time they played it was not so long.
And I often told the younger one to practice while the older one was not there.
But it was hard for her not to play it anytime she wanted to do.
Finally I decided to move it to the living room after a big argument between them.
There was another reason why I decided. Because they both must study hard for entrance exams next year from now.
Probably they will get more nervous than now and argue more if sharing the same room.
I can't stand that.
After moving the piano, it isn't as big as I thought placing it to the very back of the living room against a wall. They were glad as their rooms got spacious.
Anyway I want them to practice more and not to argue and study hard.
