I don't react much. I have had friends and acquaintences close to the industry and I simply don't really react much. I even dated some MMA coach but didn't know who he was before hand, I think it borderline insulted but intrigued him. I think it's something in your personality or not. My dad was a musician, my first real LTR was with a guy who still plays in bands, you are either too impressed or you learn to be around these people. One of my clients is the vice president of an evil pharmaceutical company. You wouldn't know it from me here. I come here to vent. I pride myself on not reacting irl. I grew up as a teen I the Raleigh scene in the late 90s and I think there was a rule to NOT react. My best friend dated a DJ, she was just featured in an Asian magazine. At some point you learn from these small encounters not to react. My ex grew up in Vegas we lived two streets over from Pink, my friends back then were sometimes millionaires in mortgage or real estate before the bubble crashed. I think some people prepare their whole life to live among big people normally. Not in an aspiring way like I want to be you, but like in a non chalant way. It isn't the norm, I know. It's like something you groom yourself to be. But if you groom yourself to be that you can experience a lot more in the world without people staring at you. Maybe a stringent Southern upbringing actually prepares one to do ok in L.A. I remember my ESFJ friend who grew up snobby with money being weirded out by how non chalant I was. As an ESFJ in her particular realm it kind of baffled her and made her get closed to me, like it gave me power, something she didn't understand. You must understand that a lot of the rich or famous are spectacularly insecure and they just jaw drop at people who act as if their social hierarchy doesn't exist. I don't know how much to give my upbringing or my ESFJ ex for that. You treat them like people, because they are.
One person I might have to prepare myself for is Lana del Rey, I think she's awesome in concert, I am pretty sure she acknowledges everyone at her concert, she reminds me of myself in that way, like she really believes people are people and she yearns to express it to her fans. I have had guys recognize me, but I have never been recognized on that level and I am not sure I would ever want to be, I have heard she modestly thanks people for saying she looks like Lana del Rey and plays dumb. People whom I truly admire make me nervous, like a crush, I have an acquaintence who knows her but does not respect her, he's basically like a douche who got let in via the side door to one of her recordings, that happens a lot here.
But yeah, I non react unless I personally really admire someone. I try not to react. I have a friend I have known for years who apparently recently became a public figure on Facebook and she joked about it, I love her, she's this amazing real ENFJ person.
People are people, they really are, and they will respond by how you conduct yourself.
