I can't remember exactly what happened, as it's been over a week or so... But I was helping The Frog with his homeschooling and he did something incorrectly.
The Frog: [with frustration] Man! How come you're always right?!
Me: I'm not always right... But I've had a lot more time to practice because I'm older.
The Frog: I can't wait until I turn 6 because then I'll know everything and I won't have to study anymore...
