How does one forgive/forget about the holocaust?

In the poem “The Watch” by Elle Wiesel, the author wrote about this 13-year-old boy who had a bar mitzvah, and one of his presents was a golden watch. This golden watch meant everything to him, he cared so much for this golden watch. When the holocaust came his family and him buried what they cared about the most and he buried his golden watch. Him and his family were taken away from their home and was raided when they were not there. 20 years later he came back to his so called home and sneaked in the bar yard where he buried his golden watch, “despite the darkness, I easily find my way in the garden. Once more I am the bar mitzvah child; here in the barn, the fence, the tree. Nothing has changed.” After a while of digging up the whole where he knew he had buried his golden watch he opened the box that was holding the watching inside, “Cautiously, gently I take the box from its tomb.  Here it is, in the palm of my hand; the last relic, the only remaining symbol of everything I had loved, of everything I had been.” He opens the box and what he sees was the golden watch covered in dirt and had worms in it, it was revolting. He then felt himself committing a crime so he went back where he had dug the gift out from and “Holding my breath, my eyes refusing to cry, I place the watch back into its box, close the cover, and my first gift once more takes refuge deep inside the hole.” He smoothens the dirt out so it would look like he had not been there, and left his past what had happened to him inside that single box.
