Xander, getting ready to voice is immense displeasure that someone else is attempting to play with his blocks. He may not use a lot of words, but you get the idea. Indoor recess for all of the classes in the big hallway, what with the 50 mph winds and all today.
Happily playing, on his own, of course.
Forced interaction. Ms. J, one of Sawyer's teachers, trying to get the brothers to interact. Sawyer is willing. Xander, not so much. He tends to ignore Sawyer at school, to the point that he will walk right past him as though he's not even there. What identical twin brother?
Playing with (okay, along side) others. Small steps. Good things.
