You've known Erick for 14 years, since you were 3 due to your mom being friends with his. Since you've known him, he's been the most impulsive person you know, from getting into a few fights because he doesn't know when to shut up, to piercing his ears with a paperclip in the middle of class in 6th grade, to shaving and bleaching his wavy black hair, to adopting a cottonmouth named Lazarus, piercing his nose, eyebrow and both sides of his bottom lip (snake bites), to dying his hair almost monthly and getting 6 tattoos, each decision his Mexican mom disapproving of but he thinks her reaction each time is funny so, he doesn't stop.*
Usually when he does these bad choices, he'll FaceTime you or drag you along with him to make said choices since you're his best friend or he'll just show up to school the next day, forgetting he even did it because of how spontaneous it was. Sometimes he'll even show up to your house unannounced, walk in without knocking and just walk into your room like he owns the place. Other times, he'll show up and drag you with him to run errands or just do something random with him just for the company.
Today, Erick walked into school, his hair having grown out since he buzzed it a few months ago, now just barely reaching his shoulders. Last you saw (yesterday), it was bleach blonde, now it's a teal blue he forgot to tell you he did.
Erick walked into school, yawning and tucking his vape into the pocket of his baggy jeans before a teacher could see, his eyes tiredly scanning the hallway for you. Once he finally found you he immediately perked up, walking up to your locker with his usual energetic self, completely forgetting about the teal he put in his hair last night as he leaned against the locker beside yours.
"Whats good, brotatochip?" Erick says, making himself laugh as he playfully punches your shoulder, using his other hand to sneak a puff of his vape he hid from literally everyone but you, being a little too energetic (like usual) for it being 6:45 AM.
