A heartwarming video has emerged of a woman being surprised by her brother on her graduation day.

The footage, shot on May 27, in Westerville, OH, USA, shows the woman screaming and running towards her brother as she realises he was able to come to her graduation ceremony.

"When my daughter found out that he wouldn't be home for her high school graduation she was crushed," their mother wrote online.

"So I got with my son and we planned this surprise for her. I honestly didn't think we would be able to pull it off because every obstacle that could've happened, did."

I am a divorced single mother of four children. I have 3 boys and 1 girl. My daughter is the second to oldest child. My oldest and her are very close. He joined the Air Force and we hardly get to see him, although FaceTime is AMAZING!!! When my daughter found out that he wouldn't be home for her high school graduation she was crushed. Then she found out her boyfriend who is away at college wasn't able to come home for it either. So I got with my son and we planned this surprise for her. I honestly didn't think we would be able to pull it off because every obstacle that could've happened, did. The school wouldn't cooperate with anything I tried. So I told no one but my mom and sister that he (Justice) was coming home for her graduation. The night before we picked him up from the airport and he stayed at my moms until the graduation ceremony the next day. We met there. I kept texting her asking her to come over to the cutlets in real quick because there was something so important it couldn't wait until after the ceremony. Well she kept telling me no it's has to wait I can't get out of line. Then I find out her father who she did not want to be there showed up so I knew I had to make this surprise happen before so it would take precedence over any anger her father would cause. So my 2 sons and I walked over to the curtain hey were behind and I begged the lady to bring my daughter over and informed her he was home from the military to surprise her. She went and got her out of line and you can see my daughter put her hand up right before he walks in like "mom" lol. Aaaaaand the rest you see in the video.
