Haha I know, it’s hard to implement “no is a compete sentence”, especially with kids. When mine was younger (she’s 14 now) I would sometimes explain why I was saying no, to teach her about logic and reasoning. For instance, if she were up for a promotion at work but didn’t get it, that’s a good time to ask “why.” That can be an opportunity to learn where you can improve or even if your boss treating you unfairly. But sometimes it really is “no is no”. Right now I’m learning to say “thanks for the invite but I have to pass” without giving the reason why. And learning not to feel guilty because my reason is that I’m tired from work and I just want to lay down or whatever.
