I thnink celeb hallpass is different from key parties because if you decide to have an open relationship and agree on the rules and set something up with likeminded people in the community that is a very real thing that could happen to anybody and requires you to be proactive in getting your needs met.
A celeb hall pass, however, is I'll be faithful to you but if Kevin Pearson from the nanny bumps into me and also we both want to hook up, it is fine. But 99 percent of the time this isn't going to happen. It is a game. You don't live where Kevin Pearson lives. You don't know him. He is ulikely to notice you if you bump into him in public. He is unilkely to be lookign to hook up with randos on any given day in any given coffee shop. He has to meet you. Like you. Decide he's attracted to you all while not setting off your creep meter and so that you still want a hall pass with him. It is a wildly unlikely scenario as opposed to, "hey, hon, lets invite those people that we met that time over and..."
My sister met her hall pass once. She thought he was a narcassistic arse because he was in an elevator and when people got in he started pretending to read a magazine and the magazine had the girl he was dating on the cover. She literally cannot see this celeb now 20-30 years later without telling this story and how much she hates him.
I do suspect he is a narcissistic arse but I think not wanting to draw attention to yourself by reading a magazine in an elevator is fine and I tihnk the magaizne you happen to have being one with your girlfriend on the cover is not likely for normal humans but is going to happen when you happen to be dating a hollywood it girl. I mean she was on the cover of EVERYTHING at the time.
