I know far too many families that have broken up because of "Daddy who is boring". When your kid says that you know that your wife has been thinking that for even longer. This isn't just those in the start-up space. Microsoft, in their WP7 "Really" ad/social commentary already summed this up perfectly.
It's interesting how kids are so honest about their feelings. He didn't learn this from his wife, and if you think about it it's highly likely it's affecting their relationship as well. People should be more open with their feelings.
