Sheesh.

Doodle just walked into the kitchen, while I was busy horking down the fruits of the Chilean countryside for my afternoon snack, and announced that Rosebud just learned about trig functions from him.

Doesn't a Dad have a right to teach his own daughter trig functions without interference from ... interlopers?

His justification was, "She keeps seeing them in the game code at Khan Academy and she was getting frustrated about it, so I said, 'How about I just teach you?'"

All that was left on the glass when I returned from snack

WHAT KINDA FLIMSY EXCU....

Just then Rosebud trotted into the kitchen with a big smile on her face.

Kids these days (shakes head despondently)...

A father has to be vigilant at all times. There's no telling when someone is going to pop up with some coup to pre-empt his right to one of these "fabulous firsts".

To the barricades, men!

...

But seriously, if you know any kids between 8 and 12, try to push them toward that Khan coding/gaming area.

You never know what kind of malfeasance may come of it.
