You're probably the first high school boy to think he's artistic because he has long hair and attempts to grow facial hair.
Tips to maturing correctly.
1) Spare the world, play the radio not the guitar.
2) Cut your hair, shave, and do all things in the category, "proper grooming."
3) Clean your basement
4) ECW shirts are for white trash listening to too much Metalica, lose it and your 15 t-shirts featuring dragons.
5) Lose the armband, you are not in risk of someone trying to cut off your hand nor does it make you look tough.
6) Help your dad finish the basement. He could use the help, and you could use the workout.
7) You're not cool. Your dad is. Be like your dad.
