I suspect so too. Wonder if we are going to see more dirt come out about him ...either from his work or more domestic issues.
Of course, I can't prove it.......but I DO suspect that this is not his first angry outburst at the child. Kids with disabilities can enrage their parents in ways it is hard to comprehend There is the "why us " factor. Why MY child ?? there is that guilt that can come.......even if it is not warranted about the condition. Guilt that they feel the child is a burden by virtue of a disability. And even resentment that the child is not "normal"....
Makes one wonder if they have had any kind of therapy / help to cope with this situation.
