Is it necessary to ignore the thoughts of junior ones by the name of inexperience?

Nobody's perfect in this world. Trying to be perfect or trying to reach the imaginary line of perfection is impossible because I really said it's imaginary, which cannot be possible in reality. One person can grow up and become mature, but they can never reach the level of the maturity that the senior people expect from them or maybe the senior people think that they are always more mature because experience is something that plays important role. Experience helps a person to mature and it's right, but does experience can outshine everything like skills and talents even if they are junior. I guess no but I think that most of the seniors don't want to admit it. Maybe they always try to show themselves as superior.

Why am I bringing such a topic all of a sudden? Obviously, there is a reason for it. Most of the time I can make decision ignoring the emotions and in maximum cases my judgements and my insights weren't quite accurate. Whatever the reason, those things for me and predicting the optimum situation is not something difficult for me. I guess everyone can do but, in my case, much better than any other person even if I have lacking something else. It actually does not matter how farsighted I was, most of the people around me ignore my warning about the situations I wanted to alert them. They are my seniors, elders or parents. They thought I was overthinking and nothing would happen like that, but it actually happened.

They are close to me, and I know that they care about me. Instead of it nobody chooses to take my alert seriously about their situation. It happened many times and I stopped giving them penis suggestion or prediction or warning or a lot related to their situation because directly I am not going to suffer any loss for that. I wanted to protect them by alerting them, but they are the ones who didn't take my word seriously and it happened again and again. What could I do when they say I am saying that because I was inexperienced. I am already 27 and at this age at least I have the understanding about the world and how things work. I know that they can be more experienced about life compared to me, but it doesn't mean they are right always. At least I know it very well as my predicted situation arrived that they ignored by the name of inexperience.

Last night another interesting thing happened. My mother is around her 55 and almost she experienced all of the things about life, and her judgement should be taken seriously. My grandmother (mother's mother) faces some situation and she visited here. My mother giving an alert to my grandmother about an issue she may face but she straight denied the idea. My grandmother told my mother that she was inexperienced and when my mother tried to explain my grandmother became angry. I heard their conversation while using my computer and in my opinion concerns of my mother were logical and I believe such kind of situation with happen for sure unless it becomes an exception. So even my mother's Idea was also denied by the name of inexperience.

I just want to know why senior people just deny the idea of their younger ones. I value experience but it does not guarantee that they are right and younger ones are wrong? Why can't they accept in some cases their junior ones are farsighted and better. And the most irritating thing is that they still never accept the idea even if they were proven wrong several times. Does it make them inferior to accepting that their junior ones are better?
