I'm not sure the context of the statement, but I don't think it had to do with her having him teach other kids, it was more like a red flag. He hasn't indicated that he's encouraged to teach (it's likely challenging enough just to get him to work with a team -- introvert easily irritated by kids who don't get it!). I think it was more about her expressing how much she's learned in working with the kids (it's her second year).
