Out of all my YouTube subscribers (My little sister doesn't support me/isn't one of them)

So apparently out of all my friends and family. My sister is not subscribed to my channel. I have did several times but she just finds out I use her account for her to subscribe then she unsubscribes. If it was probably my cousin then she would probably subscribe to her. Cause she likes my cousin more than me. Very supportive sister right? (Sarcastic) 😂
