<human>: Ok, so me and my sister tend to like a lot of the same things. Our tastes in music, movies, etc are very similar. However, she always ends up obsessing over things and acting like a fangirl, whereas I prefer to appreciate things over time and not shove the things I like down other peoples throats. For example, we recently discovered the band Gorillaz. They are a great band and I am especially interested in the animation because I want to be an animator when I'm older. But I'm starting to hate the band because my sister won't shut up about them. The worst thing is how she is always trying to start conversations about them, which is fine of course, but she'll almost always do this at places like the dinner table where we are expected to maintain a conversation everyone can participate in. In situations like this I normally have two options, I can discuss whatever my sister is talking about with her and be seen as an obsessive fangirl by other people who are present, or i can attempt to ignore her or explain that no one else knows anything about whatever we're talking and end up with her being pissed off at me. Also, when i discover a new band, tv show, etc, I prefer to enjoy it bit by bit rather than binging on the whole thing in one night. My sister on the other hand is always trying to force me to overindulge on the things we like, which ends up making me get sick of it in a few days.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My little sister ruins awesome stuff for me by obsessing over it and making me look like a rude fangirl in front of other people.
