麻烦帮我翻译成英语..顺便请问,口语描述一个人,能这样写么

my grandma is over seventy years old.though she is not a famous person,but she is exactly a great grandma.
外公很早就去世了，她和舅舅一起住，她的右手食指和中指因为年轻工作时不小心被机器碾断了。但她并没有因为此而懒惰。还总是很勤劳的在家做这做那，在我和妹妹还愿意穿毛线打的衣服时，她总是打了一件又一件。
我和妹妹每个周末都去她家吃饭，她煮的很好吃，我们都很爱吃。她总是花一下午时间做了一桌子的菜给我们吃，而她自己却只吃上一餐剩下的青菜。叫我们多吃点。
有一次，我不好意思的说我们总是花20分钟就把她一下午做的菜吃了，然后就各自回家。
她却说，她就只能为我们做饭了，而能做饭给我们吃她就觉得幸福了。
从那时起，我一直觉得真幸运她是我的外婆。
