Sarah came running in and said , " Look at what I found! ”Over the 1 of the paper I was reading came a snake skin which caused me to jump. " Isn't it 2 ?" said my wideeyed seven-year-old daughter. I 3 the snake skin and thought 4 myself that it really was not that beautiful,5 I have learned never to appear 6 with young children,because 7 they see for the first time is elementary to their 8 of beauty and creativity.

"Snakes shed their skin because they need to renew themselves," I 12 .As is so often the case in my family,the 13 subject leads to another and another,until we are 14 something quite different.
"Why do they have to renew themselves?" Sarah asked.
"We 15 need to shed our skins,those coatings that we 16 ourselves with ," I said to my child. " We 17 some things and find other things unwanted or unnecessary. This snake 18 needs this skin. It is probably too tight for him,or he probably does not think he looks as smart in it 19 he once did. It is like he has bought a new suit."
