Strange subject for a children book. The protagonist has a wall idea to separate his rooms in two because he is tired of sharing it with his brother. He then writes a series of letter to the president to talk about his wall idea, because the president also like wall... Obviously a very political subject, but in a book for young children. I get that it could bring a discussion about tolerance, sharing, respect and all but I find the way to get there weird, clumsy and it just seem out of place to me.
