Every guy knows the bro code. Thou shalt not covet thy best friend's sister. It's in the best friend bible.
But I'm the worst sort of sinner because when my best friend's sister moves in next door, I want to break every code ever written. I try to keep my distance from her, but it's easier said than done when her rambunctious little puppy takes a liking to me and keeps throwing us together.
She's off limits, so I have to keep my paws off.
