What has a child said recently that brought a smile to your face?

A couple weeks ago my family and I went to San Francisco. After a long day of sight seeing and walking we finally made it back to our hotel. During the day we saw a lot of homeless people. My younger brother who just turned 4 said to me about the homeless people "It's really hilly here, I guess thats why so many people are sleeping on the ground cause they are so tired from walking" It brought a huge smile to my face because it made me realize how cute his innocence was. So my question to you is what has a child said to you that made you smile?
