Remember a Sibling

I guess Conrad really wasn't my sibling, but he was the closest thing to a brother I ever had. I was a single child and Conrad was my childhood friend. We grew up together and hung out in the same circles. I even had Conrad take me to my high school formals :). When we were 17, Conrad was driving with his cousins doing some "off-roading" and a tree branch struck through the car window and hit him in the chest. The didn't think much of it and went home. Later that evening Conrad collapsed and they rushed him to the hospital. He died there. It's strange being all grown up without him. I keep wondering what he would've done with his life. Would he have married? Would he have had children? Would he be proud of me where I am today? Support the decisions I've made in my life?
