AIBU to ask what's the Strangest/cheekiest thing you've said NO to?

[Sister77]

First time poster, I like the collective wisdom of mumsnetters so I wanted to check if I was being unreasonable.
Several things have bugged me recently, I've noticed I'm a "yes" person even when I really DO NOT want to do something. I even annoy myself so I read a book called the power of no and put it into practice.
So the things I've said no to this week are:

1. Shift swap (even when the guilt trip was used).
2. Lending a dress to someone who returned the last one with dubious stains on it and when I commented she said she had to go commando to avoid VPL.
3. Lending money to someone who "needed" it to buy chicken to freeze for winter?!
4. Babysitting for someone who asks for an hour then returns the next morning and moans because her kids are wearing yesterday's clothes (I should have put my own kids clothes on them) my youngest is 4 years older than her oldest!

Either I'm getting more intolerant or people are getting cheesier and weirder (is that a word)?

My ex-bf of many years ago had a lot of strange friends.

I was round his when one bloke turned up. Ex had left the room and the bloke asked me if I'd be a zombie nun in a porn film he was making. Apparently I'd be buried under leaves and have to emerge, then have sex with him. Surprisingly, once I regained the power of speech, it was a Hell no! (My ex found it very funny when I told him and said that that friend was rather dodgy)

oh no, I didn't think you were having a pop I am just embarrassed to be on here all day. Even more than usual but there is nothing else to do and I'm so bored, everything's boooooooooring
