A little kid fell in love with another little kid, a school mate. 

有个小孩爱上了另一个小孩，对方是学校的同学。

Sometimes the kids think they fall in love when they have a crush on someone else in the class, when they’re eight or ten years old or something like that. So the eight-year-old kid came back home and asked his father, “Father, is it expensive to be married?” And the father said, “Yes, son, it is very expensive.” So the son asked, “How much does it cost?” And the father said, “I don’t know, son. I’m still paying.”

八岁或十岁左右的孩子有时会迷恋班上某个人，然后就以为自己恋爱了。因此这个八岁的小孩回家问他爸爸：「爸爸，结婚很花钱吗？」爸爸说：「是啊，儿子，非常花钱。」儿子又问：「要花多少钱呢？」爸爸说：「我不知道，儿子，我到现在还一直在付钱啊！」
