As another dad, I'd like to throw out a tip. There's nothing more boring than hearing someone complain about work. So don't.

I make it a rule to never talk about work unless it's something interesting or funny. For whatever reason, this works for me, and keeps me positive and fresh for la familia.

At this point in time, it's useless to ask my family to observe a 20 or 30 minute rule. I get tackled the minute I walk in the door.
