Try Not to Sob at This Video of a Young Girl Asking the Man Who Raised Her to Adopt Her

Though he's not her biological father, Ryan Farrell raised Misty Nicole Knight — he took her to her first rock concert, he did her hair in Princess Leia buns when she was younger, and for a number of other reasons, Misty says she can't imagine not having him in her life. That's why she presented him with a touching letter leading up to a surprise that literally rendered him speechless and took his breath away — she filed a petition for adoption to make him being her dad official.

Watch the sweet video to see his reaction, and just try not to sob along with Ryan during this special, life-changing moment.
