If you were a fan of a celebrity, you met them, and they acted like a jerk

Wow. That's a lot of hypotheticals to cover. Okay, assuming I actually am a fan of a particular celebrity, I'm somehow in a situation in which I meet them, and they, for whatever reason, act like a jerk (I guess without actually being a jerk?), I probably would still be a fan. I would only be a fan of someone I actually like the work of. So, I could still appreciate the work, despite my encounter with the person. Being the somewhat logical person that I am, I would also note that the celebrity may not always be the way they acted on that day.

If I incited their acting like a jerk, I would definitely still be a fan because then the whole thing would have been my fault. I shouldn't dislike others for something I caused.

Jam it back in, in the dark.
