I had two gatecrashers at my wedding. My Japanese friend had visiters from Japan over. She apologetically turned up asking if we minded them seeing an English wedding and they would just stay for ten mins and then go. One of my best friends had dropped out the day before (gave birth early) so my mum insisted they took their place and they stayed in friends expensive hotel room (where we were getting married) grin
Aww, that's lovely, Devilish.
My ex and got married in secret on Christmas Eve. We had a party on Boxing Day that all our friends and family were invited to, which was our sort of wedding reception. My SIL rocked up with her MIL (who she knows I can't stand) and some other old biddy we'd never even met.
I was bloody pissed off, having this whiny, moany old woman and her even moanier friend spoiling our celebration, but I took it on the chin, even when they were horrified that the dog was allowed on the sofa and went and sat next to them. No-one would ever have suspected that I was pissed off though, I made them welcome, fed and watered them and treated them like I would any other guest.
A few days later, I spoke to my SIL & BIL, and asked them not to bring her along to an social event of ours that they came to without checking with me that it was ok.
At another party I had, a girl I didn't know awfully well rocked up with her new bloke. He was someone I'd had a shortlived thing with a few months earlier, and we split up on very bad terms. I think he was more embarrassed than me, and when introduced I just smiled and said "Yes, we've met before, nice to see you. What would you like to drink?". It wasn't easy (I was itching to say "Fuck off out of my house, you cunt") but I didn't want to make a scene in front of guests, so I acted like it was fine.
Oddly, acting like it was fine made me feel as though it was fine, which is weird.
