I thought Kinder Eggs were the eggs laid by chickens. As such I tried to steal my aunt's so I could have an unlimited supply of chocolate.
What in the world made you think that kinder eggs are the eggs laid by chickens?
I read it on Wikipedia when I was younger. I truly believed it and I should have double checked elsewhere.
Since Kinder Eggs are modeled after the shape of actual chicken eggs, it is understandable to be confused about their origins if you were a kid and had limited experience with the world. You shouldn't feel bad that you were tricked after reading a misleading Wikipedia article, but you should feel some guilt about wanting to steal from your aunt as stealing is wrong. Now that you know, you should revise that Wikipedia article to prevent others from being misinformed like you were.
It's not my fault I was a kind and stupid enough to believe that article.
I believe now that you are older, you have the chance to make up this mistake you made, then. Why not tell your aunt and apologize for what you stole before, and since it's a interesting story, maybe she'd be entertained instead with your misinterpretations!
