The other night in one of my books clubs, for some reason we started discussing sibling relationships and how younger siblings look up to older siblings. One member talked about how she got annoyed when her younger sister copied her opinions because she wanted the sister to think for herself. I can think of a number of movies/books/shows that I decided I didn't like because Kathy didn't. I have no recollection of what I actually thought of them; Kathy didn't like them, though, so I didn't. For example, E.T.. I remember seeing this and being weirded out by the government guys who come. Beyond that, nothing. But Kathy hated this movie. So I did, too. And for a while I hated Evita because Kathy did, but I got over that. I love that musical.
Of course, then came the backlash: If she liked something, I hated it. The example that springs to mind is when she was really into Journey. I would protest listening to them just because she liked them. Ignoring the fact that I don't mind them.
Now we're at the point where we do like most of the same things, but slightly diverge at points (she doesn't like Will Ferrell; I avoid most sci-fi), but it all works out in the end.
Current song in my head:
