Why do people expect me to change in a negative way when I grow up?

Naturally, my personality is a positive one. I'm an optimistic person and I try my best to stay on positive side.

I have already passed that immature and hatred phase. I'm not going to barge but I am mature enough to understand that there is nothing in sticking to hate. It must seem like a joke to everyone because I'm still a kid but does my biological age really tells about my mental age?

Honestly I'm tired of people trying to convince me that I will change a lot (in negative way) when I grow up. Not only me but other teenagers who are positive like me also go through this. Is it important that everyone have to change?

I already have plans for my future and even back up plans incase anything goes wrong. Basically I have an idea of how I will spend my rest 60-70 years of my life. I am prepared for the worst. I know actually how negative world can be because I'm one those who is exposed to the dark side of the world. I wish I wasn't.

When I will say things like "I don't hate anyone" "I believe love is more expensive than money because you can't buy it" "Everyone deserves fair chance" And all then I will get replies like "Wait till you are an adult" "You are still a kiddo so shut up" "Life isn't a fairytale you are expecting it to be".

I know there will be times when life will slap me so hard that I would just want to eliminate myself. I know that there will be times when I will doubt my existence. When I will feel like I don't have a heart with feelings. But those who are strong to face it can only put themselves together and continue life after sticking back their heart with positive glue.

There are two types of people, one who grow up from a bad situation only to become heartless people. They basically loose themselves after series of events that happen with him. They don't want to get themselves back together anyways. One who grow up from bad situation to be stronger than before and have the most beautiful heart ever. They actually learn from what happened and ate brave enough to move on and paint the blue (depression) of the past in white (peace).

I believe I will learn and move on because that's how I'm raised up and it's just set inside me to do so. Why always demotivate positive youngsters instead of motivating them because their mentality is actually what a good attitude should be?
