REMINDER! It's allergy season.

You're probably gonna wanna watch this alone. For Kalani Watson's 10th birthday, his family was spending time together. But the lil dude is the one who gave a huge present to his step-dad, Brandon Williamson.

Kalani essentially says Brandon has always been a father to him, so why not make it official?

You can tell the moment that Brandon realizes what's coming. He tries to hold back the tears, but when Kalani says the words, there was no holding back. And rightfully so.

Kalani's mom, Porsche, uploaded the video to her Facebook page. This might be the sweetest video that's ever been put on the internet.
