how can I get along with people are to immature?

First of all, don't worry. It's perfectly normal for good دوستوں to have different personalities. :)

If this childishness is causing tension between آپ and your friends, I'd suggest آپ focus on what آپ do have in common with them. What hobbies do آپ have? What TV shows and موسیقی do آپ like? Find a common interest and take it from there.

Being mature does not make آپ "lame"! It's important to just be yourself. If آپ spend your teen years pretending to be someone you're not, آپ will regret it when you're older, so be true to yourself. If your دوستوں try to pressure آپ into changing your personality again, try asking them, "why can't I just be me?" It might not seem like a very complex question, but it might help them realise that trying to change who آپ are is wrong.

Think back to how آپ became دوستوں with them. آپ mentioned that آپ pretty much get along, and that's good! So, why do آپ get along with them? How did آپ become دوستوں in the first place? There's obviously some reason آپ two can get along well, so focus on that too.

So, long story short: find common interests, remember why آپ are دوستوں in the first place, and be yourself!

Good luck! :)
