Sibling Being Picked On

I would be as nice to her as you can. Include her in your activities. It doesn't seem to be bothering her, right? Maybe she DOES realize it and just doesn't care? We all should be happier.

Well, its good of you to be concerned about her and her well being....

the main thing you can do, is to be there for her/lend her an ear, if she gets picked on or Bullied.... bullying, is not allowed in schools. MOST schools have a "Zero Tolerance" policy... and it is strictly enforced. If she gets bullied and it is chronic and bad, it can be reported to her Principal/teacher/school. And document it and the events.

Are your parents concerned about it too?

maybe practice with her, about things she can say... to people who are mean to her... give her actual sentences she can use and say... and how to "stop" someone from causing her trouble.... and how to, tell the Teacher if need be.
Some kids, don't know they can speak up and SAY something to the offending person nor to the Teacher. Or they may be too ashamed....

And maybe as Denise P. said, she is just an optimistic person, who doesn't let others get her down....

And, converse with her, talk story with her, about school/her feelings etc. so that you can gauge her situation and any peer problems if any. Then that way, you can be alert to it, and see if there are any red-flags or not... and then help... or get help.

Does she have friends? Or is she alone in school? having good friends are important... because maybe they will stick up for each other and have each others back.

Again, you are a good sister for looking out for her.

I feel with you, N., since my sister was the same. When we were younger, I got in all kinds of fights trying to protect her. Looking back, that was not the way to go. The best thing you can do is believe in her. An older sister who trusts in the inner strength of her sister to handle the painful situations life throws at her is very powerful and helpful. Talk to your parents about the situation to make sure they are aware of what is going on and can help if things turn dangerous. You can be there for her if she wants to talk or get advice, be the rock she knows she can turn to, but ultimately she will have to handle most things herself.

Have you talked to her about it? Does she think people are being mean to her? It's very scary to ignore it especially if she's starting high school. Sometimes people that seem happy & not bothered by being picked on are really hurting inside & may not know how to deal with it which can result in her hurting herself. This is not something to just ignore. So talk to her about your concerns & see if she is hurting more than she is showing.
