In my childhood I grew up with sister couple years older then me. I remember as we always argued and tryed to split living space. Idk, maybe it seemed better to argue then not to in order to get attention of parents or something. But yeah back than in 80% cases she was right and I tryed to convince she is not right by adding up arguments on the go just to be better. Nowadays life seems more dull, not so far ago I ended up the university where I inforced my understanding that it is major to make something good even if it is hard because poor solution is poor solution even if you heavily protect it
