Answer the question about text:

So as I was stalling , asking her dumb questions , as were the other parents , The Little Man all of a sudden got sad and started to whimper . What ! This guy , that could care less if we were leaving her to go home and play some train by ourselves . This guy , that did n't like sharing Play - Doh and all the tools that come with it with his silly sister .

What may be the reason our little man reacted like that ?
He does not like to share .
