"A heart is like a broken mirror. It is better to leave it broken than hurt yourself to fix it."
The actual quote was from a young girl's conversation in the academy that I had been eavesdropping in on; who, incidentally, happened to be one of my favorite cousin's fangirls. Rejected fangirl, to say the least.
Itachi was never the cruel type when it came to girls; it was one of the many little things I admired about him. To be so confident and have your plans sorted out neatly if a female was approaching was definitely commendable. He was probably the only person that had a great deal of self-assurance and was modest about it - but hey, I was born and raised in the Uchiha.
You're probably thinking something along the lines of, "..Never the cruel type? Shisui, the girl was heartbroken. How is that not cruel?"
In actuality though, the saying is self explanatory. Itachi put rejection in a way that, with however much grace necessary, left a girl complacent. With willingness to comply with his decisions.
The girl that had been ready to confess to him - brave yet scared to death - left the situation completely understanding.
That day, as soon as the academy's lethargic bell rang, I rushed home. As fast as possible.
...And to prove what?
To prove to myself that, by all means, a broken heart is not worth fixing.
I stopped trying.
