I’m 17 and I still have a screen time while my 14 year old sister doesn’t.

This is stupid. I’m not in my phone all day while my sister is on it almost 24/7. Ever evening she is on a call with her friend for like 5 hours and my parents don’t say anything about it. But if I’m on my bed for 5 minutes on my phone I get yelled at. This is so stupid and annoying
