Do you ever just start casually rooting around in someone's likes/interests/followings and realize there's a part of them you never knew about? Has it ever made you reconsider a lot about what you thought you knew about them or changed your opinion on them? Have you ever considered seriously adjusting your relationship with them since you don't think you'll ever be able to provide them with what they appear to be interested in? What about stepping away from that person entirely based on what you found?
Because if you have... gosh, that must be a totally normal and not-at-all jarring experience or something.
