That first song is one I think of often. Whenever I am busy with other stuff and my boy is saying, "hey papa, hey papa..." I sometimes have a moment of irritation then think, 10-12 years from now when he's too cool to talk to me, will I say, "well I'm glad I spent that extra two minutes looking at that amusing youtube video"?
I turn him aside if I am talking to his mother, because listening to his mother and women is an important skill for him tolearn, and also sometimes when working, because when people have 100kg on their backs I have to pay attention, and this is after all how I pay to feed the boy. But apart from that...
