Their moods change suddenly and without reason and warning. You can be laughing and baking cookies one moment, and then they're screaming loudly at you 2 seconds later because something (their own schizo thoughts) triggered them and you, a normal person, don't understand why they're screaming at you and telling you you're a piece of shit etc for picking up a mixing spoon. You try to keep making cookies. They might flip back to being nice within a few seconds again, or in five minutes, or tell you to go fuck yourself and your cookies and leave the room.
They'll come back in the room to remind you you're a piece of shit, and if you offer them a cookie to be nice, they'll shit all over the offer to make you feel as bad as they do. Or the opposite happens. They chew you out so bad, you just try to hide and mind your own business, but a few minutes later they're hanging all over you telling you how they love you so much and smiling and saying they'll make tea to go with the cookies, and they never even mention the little episode that just happened. Because in their mind it didn't happen. But also, they were in the right, so of COURSE you're not going to mention it because they've corrected your actions, whatever they were. And if you do bring it up, they'll fly off the handle again because how dare you remind them of something uncomfortable and imply they did something wrong!
The lack of stability (you never know what you're getting, it's mostly random so every action from the biggest straight down to saying hello is like playing Russian roullette) and reinforcement that whatever you do is wrong really fucks you up as a kid, if it's a bpd parent. As a kid handling a bpd person, it teaches you you are literally never safe physically or emotionally and nothing makes rational sense. You live in a minefield of over the top reactions, and you start focusing too much time and attention on how to avoid flare-ups instead of living your own life.
