<human>: My brother and I are twins, and we have an older sister. I've had a few boyfriends before and she didn't care at all, if anything she was proud of me and thought it was cute that I'm growing up or whatever. But my brother is dating his first girlfriend now and she cares so much about it. When she first met her she posted something on twitter like meeting her little brothers gf and wanting to scare her. But she was always nice to my boyfriends, I'm not saying I'd like her to be mean obviously but it just seems like she doesn't care about me as much. Like she is always asking if things are okay and worrying about him, talking about like red flags to know if she is bad or something, and it makes me feel like she doesn't love me or she just cares more about him than about me and it makes me kind of jealous. 

Is this normal? I think we're equally close with her and she doesn't mistreat me or anything but I don't feel like she is as protective of me as she is of him even though him and I are the same age and we're both her younger siblings. Should I tell her about this or just let it go?

Can you provide a brief overview of the text?
