100% yes. People who are more open make great friends since we are able to bond quickly, but the "burn-out" just happens much faster. If I'm going to be "required" to spend a lot of time with someone, and commit to being close with them (friends are different- friendships can get closer and further and it doesn't matter so much) this obviously can't be the case. There's also obviously the case of "a challenge". With girls who are more open, I'm likely to figure out where I stand very very quickly, and then it just loses its excitement too quickly. I feel like mysterious girls force me into the correct pace and slower build up which is what I need.
Mysterious people are also more introspective in general, and that's important to me.
