That doesn’t sound like her getting spooked because you didn’t have an insta, it sounds like she got spooked because instead of being straight up and going “I mean, I do, but it’s old and I never really used it at all” you got weird and made up some weird BS about it.

And I know it’s that because not only would it make me raise an eyebrow if some random did something like that to me, I always tell people “Unless you’ve got a Whatsapp, its either text me or call me. The two social medias i have are ancient, I barely used em in the past, and the logins are lost to time I’m pretty sure.” Never given people weird vibes or anything by being honest like that, and we more often than not have a pretty nice time.

Also, being mindful of one’s privacy does not make said person anti-social. I’m pretty protective of mine, but i still reach out and talk to my friends and family near daily via face to face or messaging, am pretty receptive to a stranger or acquaintance wanting to have a chat or a coffee with me after work, all that jazz. That I don’t like the thought of Meta, Samsung, Google, and Microsoft snooping around people’s info, trivial as it may or may not be and thus distince myself from them (within reason, mind. I can cut myself off completely, but that’d be making both life, work, and everything inbetween too much of an unnecessary hassle), doesn’t diminish any of that.
