I noticed my sister had some stray hairs on her head, so I'm going to get rid of them by pulling on them, but she wants them to be left alone.
Why would you do that to your sister?
She is such a control freak.
That doesn't mean you should pull her hair. That's wrong because it's her body and her rules. You should tell her about the stray hairs instead and let her decide what to do about them.
I think it's faster for me to just pull them.
That's not your choice to make. Don't pull her hair.
