I remember a girl in a fandom I was in sliding into faker territory with a story about running into David Duchovny at a gas station (or maybe it was a super market) late one night, and having a pretty fantasy level chat with him. She didn't go as far as to say they became friends, or he asked for her number, or anything. But it was still a very idealized scenario, in a way that made many of us 99% sure it was made up.

It was a weird one, because she was fairly popular in fandom, and for the most part was friendly and fun to talk to and, well, normal. But I guess her need to feel...idk, cool and validated? got away from her now and then. To my memory, nobody confronted her and accused her of lying (which I'm glad about now) - but we had some private conversations about it among ourselves.
