On/off phases mostly. Usually back and forth mildly for a week or a few days. Then silent for a few weeks. My sister I use to open up more and talk about more personal things. Not anymore though as she has been much more distant the past several years. My brother I talk to him mostly to bond with a game both of us have been playing, usually nothing more beyond that. Occasion it will branch off into us talking about more light personal stuff. But he usually just cut off whenever it starts hovering into those areas.
My brother and sister though, I know they talk constantly and are much more personal and opened with each other. Since they're much closer in age, and they respect each other more, and see each other more as peers and pals.
The truth is strictly what the ones in power perceives it to be.
Enjoy any good things, even the little and menial ones, as you will never know what impending distresses could descend upon you in a moment.
