I am proud of you for realizing, at your young age of 14, that one of your roles in your family is to protect your younger sister. However, if your sister is teased again by older kids while walking home from school, do not fight them. This time, take your sister by the arm and head up a different street, away from the bullies.
When safe at home, talk to your sister and tell her that you and she should speak to your parents again and let them know the teasing continues. You said the other kids live a few blocks from you. Perhaps your parents already spoke with the other kids’ parents. If so, did they meet in person or just talk on the phone? Ask your parents to meet face-to-face with the other parents. Perhaps all of the kids involved, including you and your sister, can be present in that meeting. Say how the teasing makes your sister and you feel.
Talk is always better than fighting. Plus you will avoid a second black eye!
Good luck and please write again.
