I am a very sensitive person. So I try not to hurt others feelings, even if that means I have to "bend over backwards" to not do it. I do make my mistakes, though, and I encourage people to tell me when I cross the line on something. I will try my all to fix it! :-)
I've been around so many who didn't care about my feelings, growing up and even today as an adult, it still happens. BUT, each time someone is uncaring to me, it makes me better at being caring to others. Because I've been hurt in so many ways, I know what NOT to do to others. And I'm more understanding of a lot of situations too, because I am able to feel what the person is feeling.
So, with everyone that I meet, I do care about your feelings greatly. I only stop caring, when you stop caring about mine. Which is only fair. :-)
