A recent college grad got the shock of her life when her dad surprised her at her graduation.

Ruby Robinson, a graduate of the Columbia Engineering School, assumed that her father, U.S. Army Reserve Captain Keith Robinson, would not be able to attend the ceremony due to deployment in Afghanistan. 

Watch the surprise here:

Capt. Robinson was able to take a leave from his unit, which had been deployed for the last six months, and fly to New York for the ceremony. As Ruby walked across the stage to shake hands with the dean and president of the university, her dad was waiting just off stage to congratulate her.

Wonderful.
