How many people are still the same old person they were in their teens?

I would say about close to everyone has some child left in them.

My uncle is 59 and still acts like a teen.

He binge drinks, makes messes and doesn't clean up after himself, lives with his elderly mom, gets upset of you dare disagree with him, tries to date as many women as possible.

All this while claiming to be a Christian.

And to top it all off, he dates women in their 20s who usually are unemployed a/o addicted to drugs. 😢😢😢

From my experience, I would say no one ever really grows up, we all just get older.

ive been hanging around this site and this section since i was around 15. ill be 24 next week and i can tell you that i am much different than i was when i was a teen

Very few.
