Tell you how to be a dad-like thing person? Oh boy, now there's a difficult question. Mostly it's a lot of trial and a hell of a lot of error. Luckily people start as babies so the biggest screw ups they'll never remember you making. You've still got a few years there with the Daria's girls before they start realising how much you can mess things up, and even then they'll still barely notice until they're teenagers. Then all bets are off.

In the end it all comes down to just loving them and just making sure they know that.
