This is a must have in my classroom because students need to know that is okay to have a bad day. One thing that I think adults so often make the mistake in doing is to think that children cannot have bad days, but yes they can and they need to know that. When they understand that they can have bad days, they understand that other people can have bad days and they are more understanding. The book is great to read because it seems as if the smallest things get to Alexander and that is okay. I would love to read to this to students at the end of the day and then have a discussion about tomorrow being a new day!
