La Hermanita de Pingüino

So, today my little sister got in a car accident because her boyfriend broke up with her over something as ridiculous as a haircut.  They'd been together for almost two years and she cut her hair and he broke up with her.  She was so upset that she was crying while she was driving and she rear-ended someone.  This little prick threw away a wonderful girl over something as trivial as a haircut, and why? Because she didn't tell him before she did it that she was going to.  Are you kidding me?  Why does it matter? It doesn't change the girl you're in love with.  But no, you had to throw it all away over some hair.  This has created havoc for her, and this is probably one of the worst weeks of her life.  Thanks.  Way to be a prick.
