编辑同志: 不久前的一天下午,我放学路经一幢即将封顶的大楼时,一块木板从天而降,我躲闪不及,被木板砸中,倒在地上。当我醒来时,守护在病床前的妈妈说我已经躺了三天了。为治我的伤,父母一共花去医疗费4500多元。父母要求该大楼施工单位赔偿,但对方以木块是大风刮掉的,自己并无过错为由,拒绝赔偿。请 Editor's Comrade: Not long ago afternoon, when I left for school after going through a building that was to be capped, a piece of plank fell from the sky and I dodged and fell on the floor with wooden planks. When I woke up, my mother guarding the bed said I had been lying for three days. To cure my injury, parents spent a total of more than 4,500 yuan medical expenses. Parents claimed compensation for the construction unit of the building, but the other side of the wood is a strong wind scraped off, there is no fault of their own grounds, refused to pay compensation. please
