A 10-minute video of Klein being taunted by the boys was posted on YouTube this week and spawned a fundraising campaign titled "Let's Give Karen The Bus Monitor a Vacation." The drive brought in more than $500,000 to be donated to Klein, CBS News reported Friday.
However, Klein said she just wants an apology from the boys who bullied her to tears.
The boys' parents have apologized and said their children will be punished for the incident.
"There's no excuse. And we're going to get to the bottom of that but it really broke my heart and I shed a lot of tears thinking about that whole thing and I just want you to know that my family, all of us, are deeply saddened by this whole thing and we're going to get it right," said Robert Helm, the father of one Klein's bullies.
Klein said she understands the incident is still raw and she may not get an apology from the boys right away.
"I would rather wait a while," she said.
