my little sister just dont know

I feel like shaking her untill she gets the point. She goes out to the movies which was paid for from the school. And she askes for 10 dollors i give it to her. Then she came in today and we found out that she had 20 dollors to buy food. She keep saying that you have to have 20 dollors to eat/// Now I know most of you who follow are in college and you understand the crunch on money, have you ever bought a meal for 20 dollors.... I dont even pay 20 dollors when I go out to eat.

And this is why i dont wanna have kinds. I would be beating her ass right now.
