Susan Klebold, the mother of one of the students who committed the Columbine High School massacre, wrote an essay for the current issue of O, the Oprah magazine.



Klebold, who's had very little media contact since the killings, opted to write the essay instead of doing an interview with the magazine.



In her piece, she offers insights like this:



"For the rest of my life, I will be haunted by the horror and anguish Dylan caused. I cannot look at a child in a grocery store or on the street without thinking about how my son's schoolmates spent the last moments of their lives. Dylan changed everything I believed about myself, about God, about family, and about love."

It's attracted mixed reactions.



Some say Klebold's essay eases the healing process.



Others are more critical. Here's a reaction from a Denver Post columnist:



"The article was heartbreaking to read, but maybe not for the reasons you'd expect. Klebold wrote too much and, at the same time, revealed so little. It's not just that she tells only her side of the story. It's that you know while reading it, there's so much she either doesn't see or doesn't want us to see."
