One of Those Days We have all had “one of those days”. This picture book supplies cute descriptions and darling illustrations of a vast number of events which turn a potentially great day into “one of those days”. The expressions on the faces of the children who are experiencing less than optimal days – “itchy sweater day”, “fun thing canceled day”, “answer to everything is no day” really capture their frustration. The book ultimately reassures the reader that even though it may be “one of those days” a new day is soon to come.
