Are there any gadgets or instruments to measure our maturity?

My family and friends have been telling me that I’m childish and naïve. Yes I know. Sometimes you just want to live in denial. Who wants people keep reminding them 24/7 how immature they are?

It gets annoying as if you don’t have your brain to think like how the adults think you should think.

How can I prove them wrong?

Maybe they are just too right.

I do not have a patience of a saint.

Good night people!!
