Ignorance is bliss.
모르는 게 약
May: John, do you happen to know where I put my small shopping bag when I got home yesterday? 
John: Uh, I think you threw it away with the trash bag. Why are you looking for it? 
May: Gee, I can't get my money back then. 
John: Why? What's wrong? 
May: You know, I bought this violet coat yesterday at this J.Vim shop. 
John: Yeah, your coat is still in the closet. It looks so good on you. What about it? 
May: I happened to stop by the shop again and the price was different from yesterday. 
So I asked the clerk and she said it was a mis-tagged price 
so I have to bring the receipt in order to get the balance back. It really pisses me off because now I can't find the receipt! 
John: Oh, well. It seems there's nothing you can do about it then. Just forget about the price you saw today. 
May: I wish I could do that too. Well, that's why it's said 'Ignorance is bliss.
