Why do parents think they know everything?

Because parents are much older, they've gone through a lot more. They try to use their limited experience and their biases to guide us towards what they think is right. A lot of the time, however, it isn't. At the end of the day, it's always important to respect and to consider what they're saying- but only you can make your decisions.

I don't think parents think they know everything, I don't think anyone of us feel like we know everything it just may be a personal misinterpretation. Also, in certain situations they wish to impart knowledge they have gained from an experience they have had. Your situation and their experience may sound completely dissimilar and thus you gain a feeling that they "think" they know everything; but in reality they may know a little more than you do and see a connection they wish to share so you don't get hurt or go through difficult time periods that they have had.

Because that's how they been raised. No but parents know a lot of stuff so listen to them that's the best

Parents think they know everything because they've already faced a lot of the problems their children will face in life.

Parents only try to help you make the right decision, something that can help you continue life at the fullest. They might seem bossy, rude, or like they don't make any sense, but a parent's only goal is to make your life easier, safer and happier.

Your parents are older and wiser. They have more knowledge and understanding. They might not know everything that is necessarily going on in your life but they only mean well for you. They could be just trying to help you with your situation.

Because they're older and wiser and have more experience living in the world than kids do. It's like that with most adults I think.

I know you don't like it but they have more experience in life and they don't want you to get hurt like they did.

Your parents are older and wiser and surely they are giving you advice from their experience because maybe they went through what you are going through, they faced what their children are facing. So they might be rude or bossy but actually they just want to help you

Adults always think they are right in everyway and that they are doing the very best for their children because they lived longer and therefore think that they have more experience and understand how life works better than teens do, witch, loads of times, its not correct.
