I think that part of his problem is that he lets his kids treat the wife like dirt.
She has allowed it as well, but it seemed she was getting not only sick of it but embarrassed as well. Wish she wouldn't have sucked up to them when it turned out they made it in time. Yuck!
What's amazing to me is that this is the FIRST day and they aren't even trying to be polite on camera. Imagine how they are going to be when the nerves get really frayed in some place like India.
