Re: Why take joy in hurting others?
My thoughts are that she might be jealous - unknowingly. It happens sometimes. We dont know or even notice it and we say things that might hurt others.
She is your sister, if you ever needed a kidney...she would give it. If you were stuck in the middle of the highway, you would call her. If you needed money for some sort of unexpected reason, she would take care of it if she could. God forbid any of this ever happen. The thing is, she doesnt intentionally say things to hurt you or want bad for you...but she is jealous and she doesnt understand it which is why it comes out in such mean and impulsive ways. I dont think she understands the weight of her comments or the effect they have on you. She thinks you're a lot tougher then you come off.
Two things you can do:
A) Talk to her. However, if you talk to her you have to solid examples to show her she was wrong. Be prepared to be open, honest and also understanding. She may open up to you and tell you what the issue is or even apologize and stop.
B) Smile, nod and keep walking. Develop a thicker skin and realize you have your own life ahead of you that you have to worry about. Thinking about these petty comments does more bad then good so lets not. If she says something mean, answer her with a compliment. No, Im not asking you to be Mother Theresa...you can actually guilt her into stopping and avoid confrontation. After a while, people will notice and think she is nuts for being so rude when you're so nice to her.
Good luck sister and congratulations on your life ahead of you!!!
