@andrewhan8 No, entering an institution sooner does not necessarily mean they studied more. I could have entered school 2 years earlier than you and never studied, therefore saying that it is basing on how much they studied doesn't go.
That is why 선배 has the responsibility to uphold, to study more and know more than their 후배.
The reason why korean people respect the elders is because being older means they have spent more time living which means they have more experience, which means they know more. They want to honour this.
what you are saying means that they should stop respecting elders too, since spending more time doesn't necessarily mean you will be studying more.
You originally said someone who "studied" more than you is your 선배. And I said experience and timing, not you.
I study more than someone that is at a higher grade than me. I study for 4 hours a day, and my friend that is a grade higher than me studies for only 2 hours a day. Does that make me his 선배 now? No. Because he is at a higher grade than I am, and has more experience than I do.
You're either purposely twisting my words or just misinterpreting them.
I hope you're realizing, you're now just repeating what I'm saying.
