Who's the boss?

A protective and caring sister who gives her baby brother advices every two minutes and voluntarily reminds him when he's driving to keep one lorry-distance from the car in front, to hit the brakes when turning sideways, and to not dare go more than 90km/h finally receives one simple line;

"Kaklang, you sound exactly like Mama."

And so she replied,

"Why, thank you. "

It's good to be in charge. :)
