A 21-year-old in Tennessee had a lot to be thankful for this holiday weekend after she received a bouquet of birthday flowers from her father Michael--despite the fact that he died five years ago. "My dad passed away when I was 16 from cancer," Bailey Sellers tweeted on Friday along with a pic of the bouquet and an old photo of her with her father. "Before he died, he pre-paid flowers so I could receive them every year on my birthday. Well, this is my 21st birthday flowers and the last. Miss you so much, daddy." Sellers also shared a pic of the handwritten letter left behind by her father for the occasion, which read in part, "I will still be there through every milestone. Just look around and there I will be. I love you, Boo Boo, and happy birthday!"
