This heartwarming Father's Day video will make you cry ugly tears.

Sophia Kallie took to Twitter to share a video of her stepdad opening his Father's Day gift. She said during middle school, he would leave her a note on her door every day to "inspire me."

Kallie kept those notes, and for Father's Day she gifted him back six years worth of inspirational messages. 

In the video, her stepdad appears speechless and starts crying as soon as he unwraps the gift. Kallie had framed dozens of yellow sticky notes around what appears to be a photo of her with her stepdad.

"I kept them all," Kallie says in the video.
