wife, he doesn't even know what to say, this is a catastrophic event for this family, and specifically for him. but here's the issue. we don't know how the father typically handles grief and being upset. so in a case like this we would have to go back and see how we handle loss and grief and terrible events in his past. this may be consistent with that. and of course the stages of death and dying are very complicated, and frankly, he could continue to be in shock. he doesn't even know what else to say. but i think as the days and months go on i think we're going to see and hear different sentiments come out. >> mary ellen o'toole, thank you for helping us understand the incomprehensible tonight. appreciate it. >> you're welcome.
