I agree that Brendan didn't come across well at first with Tom, he didn't have a lot of tolerance when he couldn't understand him. Saying that, I liked his comment on people's homes, he said it doesn't matter what people's homes are like as long as they have the basics such as warmth and comfort (I'm paraphrasing), that was a nice thing to say.
It would be nice for most schools to have an additional learning centre or suchlike so that all children can play together regardless of disabilities, from experience it makes for a kinder and more accepting child.
