This story was sweet.  It’s a great vocabulary lesson without being preachy or repetitive.  Sam and Dad are a pair.  But things happen and Dad wants Sam to consider if it is a “big” problem, or a “little” problem and how to tell the difference.  The art work in this story is unique.  The illustrator does a great job of portraying emotion and action in a still work. This book just works and would be a great edition to any library.
