求翻译：我最愉快的一天。我最愉快的一天的就是小学同学聚会。他们变了很多，有的变漂亮了，有的变帅了。但是唯一没变的就是，我们曾经是一个小学的。那天我们玩的很开心，因为已经有很多年没有见过了，那就是我最愉快的一天是什么意思？

My most enjoyable day. My most enjoyable day is the primary school students gather. They changed a lot, some beautiful, some handsome. But the only thing that hasn't changed is that we used to be a primary school. That day we had a good time, because there is already for many years had seen, that is my most enjoyable day
