13 year old sister saying racial slurs and racial slur adjacent slur things

My dad is never around because he moved to a different state to work for a year in a really shitty job. <br><br>My mom only works bc she needs to pay for house stuff and food, and my dad only sends us money to survive and not to thrive. So my mom is extremely stressed out.<br><br>When my dad moved away, my 13 year old sister was in 6th grade. <br><br>When he moved away, she was in 7th. <br><br>And right now she’s in 8th grade.<br><br>When he moved she was a year too young to be too active on social media, so she mostly used TikTok.<br><br>My dad will be back in a year. He moved in the summer of 21 and he’ll be back in the summer of 22.<br><br>I keep asking her to stop saying the n word and other racial stuff like “I can’t do anything. I’m short and black. <br><br>And my dad moved away”. <br><br>She keeps saying stuff like that.<br><br>How do I get her to stop?
