I am in my hometown and with my parents now. I had intended to say that I am in "実家" now, but I couldn't find out the right expression.
Since the day I left my home and began to live separately from them, they have learned to quarrel. In the past, it was unimaginable. One of them went mad and shout out with their rage, and the other became silent. It was as if the whole house were waiting for the fury to settle.
But now things are different. When one of them gets angry and begins to talk angrily, the other comes as angrily. This change seems very significant to them, because they have learned to communicate with each other when communication is most needed.
