JM, please tell Jacob this from me.
Chapter books rock!
Ever meet someone and like them and never get to see them again? With short books it can be like that. With a chapter book you get to know them a lot better.
When you read a "little boy" book (sure to get his attention)

they do the pictures but when you read a chapter book YOU get to use your imagination and can imagine anything you want.
If a book is a good one it will be easy to read no matter how many pages. If it is a bad book it will be boring even if it only has one page.
I suggest that folks start with just reading one chapter at a time, sort of like a whole bunch of little books in one.
It is also difficult because there are fewer good books for boys than girls. Does he like sports? Find books about dinosaurs, sports, whatever he likes. When you find one that he likes look for more by the same author.
I compile my book lists from
Amazon.com's list of most sold books in the category I am interested in.
What a cute elevator story. Little people do not know everything that we older ones do. I hope he is not embarrassed. He was just being very well behaved.
Did you get scared with Criminal Minds? The scary thing is that they take almost all of their storylines from real life stuff.
Back to getting rid of 'stuff'. I am loving it too!
