Why are some people so private?

[Bent Snowman]

you went from "she posts pictures of herself in fancy hotels, in luxurious cars and such but never posts anything about her love life as opposed to the other people on the social media sites. "

to

"Why are some people so private?"

She just does not share one thing, that is not "so" private.

She just does not share her love life. I never have either, just not my thing. If you want to understand the answer to this question you have to realize how rooted in your own perspective your question really is, it does not make sense to someone with a different point of view even. You seem to be one of those people that shares everything and expects others to, you check facebook quite enough, ... a majority of people do this. You are so used to seeing everything about everybody that you actually find it "weird" that someone does not share something. This is not weird, the expectation that everything (especially love life) will be shared is what is weird.
