I found out I'm adopted at 18 years old! Nature vs. Nurture

I have a twin brother also who grew up with me that is my full blood, It was crazy to randomly get a text from the sister I didn't even know I had! Life is a trip that's for sure. I've heard that some people take the news that they are adopted really bad and it completely destroys their life. For some reason though finding this out, filled me with love. Knowing that I have more family out there that care about me. My sister and I have the same smile, we both have gauges, and we all smoke weed everyday. This really comes to show the nature vs. nurture. Even though we grew up with different parents in way different environment, we all have the same little quarks and temperament. Our nature is the same and when we first met it was like we always knew each other! For those of you who struggle to cope with being adopted just know that your real family is always thinking about you and thats's just more people who believe in you and want to see you succeed! What do you guys think about nature vs nurture?
