My God, the reading comprehension on this thread is shocking.
OP's friend explicitly said that the show filmed this month October 2023 and is giving updates on filming in the present tense, eg saying "I've just reached 12 questions and have won £125,000."
I don't know why so many posters keep berating the OP by saying "DUHHHH everyone knows they film months in advance she filmed in back in March and it's only airing now" - friend very obviously is not referring to something that happened in March.
The episodes filmed in March don't even air until next year. Do posters think the episodes filmed in March are airing now, and that when the friend says "I'm on the show this week" she's referring to the airdate? Because that can't be the case - there are no new episodes airing until 2024. So why would friend say "this week"? She can't be in an episode that's airing this week because there aren't any, and she can't be in an episode that's filming this week because there aren't any.
I really don't understand why the OP is being given such a kicking. If a friend contacted me all excited saying they were going to be on TV, my first thought would be "oh it'd be fun to see if I can get tickets to watch them!" Most people have never been on a TV set, and would find the opportunity to watch someone they knew being filmed very fun and exciting and a break from the monotony of everyday life. That's very normal human behaviour. I actually work in TV so I see how excited people get about anything connected to TV. A neighbour of mine was on a quiz show and practically half the village were chomping at the bit to try to get tickets, even people who weren't that close to the person, just because people find it very exciting to be able to visit a TV set and say "I know that person."
OP was told her friend would be filming the show this October, naturally googled on the off-chance she could come and watch, found info that made her think her friend is lying, and is now worried that she's being lied to. It's very normal to dislike being lied to because that affects trust; I don't understand all the people going "it's none of your business that your friend tells you massive lies because the lie doesn't directly affect you" - really? Would YOU be comfortable with a friend telling you lies? All lies affect the person being lied to even if the lie itself doesn't directly affect them, because it means the other person is comfortable telling lies, which means you can't ever really trust anything they say.
I'm not seeing anything to indicate that OP looked up tickets with the intention of catching her friend out in a lie, or that OP hates her friends. I have friends who have habits or flaws (sometimes major flaws) that drive me nuts, but I still love them. It's possible to love someone and want their friendship, but still be discomfited by aspects of their behaviour. MN is very black and white about relationships: if someone isn't perfect it's "LTB!! Go NC with your entire family!!" but in real life you might like/love someone but still think they tell porkies, and be uncomfortable with that, but still consider them a friend.
