Cat's cradle and Beach

This is the letter Newton didnt sent out.

To Jonah:
I have something to share with you. Although I was small and I do not know if that could help you, I will just say it.

I remember this is four month before he died, our family went to beach to get some sunlight and feel the summer. My family was still the same as the old days. On that day my father still wear a suit and smoking cigar. As you know my father is those kind of person that except his work, he spent least amount of time to dress him self. My sister was still the same, when we get to the beach she start to putting sun screen and telling me and my brother that we have be careful when we are playing. When I was building sand castle and I saw him talking to him self the whole the time. I remember he said, ” Turtle is swimming in the ocean.” I still do not get why he says that. Maybe he is saying for nothing.
However, I think that is what I remembered. I was just surprised he said something.
