I'll tell you why kids go to mommies, and this is from some book I read (probably something by Brazelton). Dads are for fun, where moms mean 'business'. That is, we look after their actual needs. Dads are...well, basically nonessential personnel. ;) Which is why your kids will always come to you when it's serious.

You know, I have learned to love Led Zeppelin. My kids think they are the greatest rock band ever.

I hope you guys get better before the trip.
