Without prompting, a 10 year old girl named Sophia Bailey Klugh decided to write a letter to President Barack Obama to tell him about her two dads.
It reads in part: 'I am so glad that you agree two men can love each other because I have two dads and they love each other, but at school kids think that it's gross and weird, but it really hurts my heart and feelings.'
Those two dads, Jonathan Bailey and Triton Klugh, were so impressed and moved by what their daughter had done that they scanned the letter and posted it on Facebook.
Wrote Bailey: 'This is not about President Obama - it's about what's right. So frankly, if you don't agree with the innocent, heartfelt and surprisingly straightforward position of my 10 YEAR OLD DAUGHTER, then please unfriend me because we don't actually belong connected here in the first place.'
Obama, who faces Republican Mitt Romney in the US presidential election on Tuesday (6 November), took the time to respond to Sophia. Earlier this year, Obama became the first US president to publicly support same-sex marriage.
He wrote in part: 'In America, no two families look the same. We celebrate this diversity. And we recognize that whether you have two dads or one mom, what matters above all is the love we show one another. You are very fortunate to have two parents who care deeply for you. They are lucky to have such an exceptional daughter in you.'
