Really, I think you should let her be with her friends and only her friends. She just want to relax with her pals. If you had had a long day of school, parents are being, you know, and you just wants to be just with your friends, would you seriously want your little sister to tag along? Just let her be. Maybe, if you really want to spend time with her, you could do it later. Then you’ll both have fun without interruptions from friends.
