They love books.

I caught Ben reading to Marissa and they actually sat still for a picture. He can read most anything and she is getting much better. It is fun to see them play together. When they argue it's only for a little bit - although they both have been heard to say, "I'm never playing with you again!" They just don't know what to do without the other so they seem to get over the arguments quickly and get back to playing together.
