Mate, he’s saying that as much as you love your kids, it gets old at some point to have them constantly interrupting your meetings. Sometimes you want to finish the meeting and be done with it, so you can go ahead and actually spend some quality time with them without any nagging concerns leftover from work.

What I'm saying is it might be cute the first time it happens, but for all people there exists a finite limit where it stops being cute. That limit however is different for different people. I would however feel fairly comfortable saying that N<=15 in an 8 hour period for the vast majority of people.
