Girls, WHy does my girlfriend copy me so much?

She doesn't do it like word for word copying but she copies me a lot. She posts similar posts to me on Facebook for example I put something about new years that said hope you have a good and peaceful new year and she wrote i hope you all have a good new year. Get what I mean? She like copies me. I changed my profile picture to 2Pac and she did the same. I don't wanna ask her this but why does this kind of thing happen? thanks.
