The Sharpie X on my hand stands out against my pale white skin

It says "you are a child"

With it a thirteen-year-old is equally restricted as a twenty-year-old

The sharpie X means no alcohol and it means no trust

It says "you are a liar"

With it they are making sure that you don't lie about your age to get alcohol

Is that what every person under twenty-one is?
A liar?
A kid?
