Hey, Dani, I know I've only known you a couple days, so if you tell me to shove off, that's your right... but I like you. I look after people I like. I KNOW you've got other people who've known you a lot longer and have more reason than I do to give a damn what he does. This guy breaks your heart then waves it off like it was some cute little kid's prank... They've got a right to be mad at him for hurting someone they love.
It doesn't really look like he respects you all that much if he can be that unrepentant about what he did.
