I..lemme elaborate.
First of all, I believed in "the opposite of love isn't hate; it's indifference." So yeah, I usually won't go out of my belief to hate someone; if they consciously hates me, and are shallowly so, by being indifferent they won't get me by making me angry.
Indifference never means being a passive doormat, however. For me it's more of losing the emotional connection; the attachment I previously had with someone; they mean nothing.
And when they mean nothing, you can do everything to them as long as you wanted to.
I can still attempting to be kind, I can be the most selfish bitch you'd ever seen, I can give attention if I wanted to, nor shall I give any if I didn't want to. I could cry seeing you being hurt, I could laugh seeing your pain, you have -no- rights to prevent me doing that.
So yeah, it's rather selfish and egocentric but it's all depending on me now, whether I will be good or not. >_>;
When someone consciously acts like a jerk, I somehow got this need to engage in battle. No, I'm not hating them, I'm just fighting them; sparring, perhaps. No hard feelings.
I'm not free from hatred, of course, but strangely whenever hatred visits me I'd back out from that person, maybe to the point of indifference. And questioning on why that person hated me.
