Sometimes teenage brothers can do the most annoying things.
Whether you grew up being a guinea pigs for his botched science experiments or bickered all day long, it can sometimes be easy to ignore the life-affirming bond shared.
That’s why when an 18-year-old shared a letter from her brother on discovering they were half-siblings, it resulted in even the most stern of siblings pulling out the tissues.
Pamela Lara, who lives in Houston, Texas, discovered that her brother, 17-year-old Jared Escamilla, was in fact her half-brother.
But rather than leave her fears up to chance, he wrote her a heartfelt letter detailing how he will “always be there” regardless.
“I just wanted to let you know how much I love you,” Jared wrote to his sister, which was detailed in a post she shared on Twitter.
“I don’t care what people say you are always going to be my sister, my full-blooded sister. You are the best thing that happened to me. I love you with all my heart, thank you for helping me on my worst and thank you for leading me the right way.
“I will always be there for you, just like you have always been there for me. I love you,” he added.
As well as writing her a spellbindingly heartfelt note, Jared also supplied his sister with her favourite snacks, including some cookies, coca cola and ramen.
Several half-siblings shared their tales of their bond and how the post had touched their hearts.
“When my little sister found out our dad isn’t my biological dad she was so upset for me lol she cried and held me like she was gonna shield me from it ❤️,” wrote one user.
“This letter needs to be framed. This is a gorgeous moment that needs to be documented forever!” added another.
Pamela has said that the news has “made us even closer”.
“Instead of breaking us apart, it made us even closer. He even tells me he feels bad for joking around that I was the adopted one in the family because I was different than everyone else,” Pamela told The Daily Mail.
“But despite all of that, I believe blood does not define family. And I have never seen him any differently.”
