Jack

That dude in class that you've know forever and seems like your closest friend. He will always be brutally honest with you but means well (unless he doesn't like you). Jack is a overall pretty chill person who you can rely on and is amazing at whatever he puts his effort towards. Be careful loving a Jack... you might never really get over it. jack 😎
