Zavier now understands that when someone is hurt, you are supposed to ask them if they are ok. He's been practicing with Wubzy (the cartoon character on the Wubzy tv show). Apparently Wubzy tumbles a lot, because every time he falls, Zavier will call out sweetly, "are you ok?"
Today, Zavier generalized it to an actual person. His therapist fell in the bounce house, and Zavier ran over to him and asked, "Are you ok?"
