Great sibling, terrible cameraman.

Deandro Wurangian was thrilled to attend his sister Deandra's high school graduation last week in Anaheim, California. He even decided to film the event, so Deandra could have a special video of this exact moment she walked across the field to accept her sweet, sweet diploma.

Except Deandro was so busy cheering, he forgot to film.

Deandra told Mashable that she wasn't too surprised by the video. "My initial reaction was that [it] was something my brother would do," she said.

Still, she added, "I adored how much he cheered because I didn't realize how proud of me he was." Awww.

Yeah, okay, so Deandra won't have a video of her graduation. But she will have a video of her brother shouting "Yeah! That's my sister!", which is arguably even better.

Plus, there's always college graduation — Deandra plans to attend California State University in Long Beach next fall.
