Editor's note: Joy Bunville submitted the following letter after participating in a St. Baldrick event at Park Junior High School on Saturday, April 21. The event was a fundraiser for the St. Baldrick's Foundation, which raises money to fight childhood cancers. Participants shave their heads to show solidarity with young cancer patients, who often lose their hair during treatment.I have thought about shaving my head bald for the last three years, but I just did not have the true courage to take a razor to my own head.
