What was the biggest lie you told when you were a child?

When I was a child, I went home on time every day, and then I wanted to go out to play with my classmates once, but I didn't know how to tell my parents. I lied to my parents that day, saying I was going to my classmate's house. There are some problems I can't solve, but in fact, I went out to play with my classmates. It's a good thing my parents didn't notice.
