This one time a next door neighbour of mine (I will call her Lisa,) was having a party/BBQ for her kids birthdays (they were 2 days apart,) and she invited the whole close virtually (11 out of 14 neighbours of hers,) but didn't invite us (me, DH, and the kids.) She was basically jealous of me because her pal Heather on the other side of me took a real liking to me when I moved in as we had lots in common, so she was really jealous. Especially when Heather mentioned to Lisa that she thought I was the best neighbour she'd had for years.
I went next door on the day before the party to give Lisa her kids birthday gifts and she said 'we are having a big party tomorrow' (Oh here comes my invite I thought...') Then she continued...... 'so apologies in advance for the noise all tomorrow afternoon and evening.'
LOL 'thanks a lot' I thought. PMSL.
So next day, the party started at 5pm-ish, and the BBQ began. Around 40 people were here by 6.30pm. I was evesdropping through the bedroom window, and I heard Heather say 'lovely gifts that Kim (that's me!) gave to the girls... where is she by the way?' And Lisa said 'ummm, not sure....' Heather said 'go knock and see where she and the rest of them are...it's weird them not coming, I'm sure they're in.'
2 minutes later, neighbour Lisa knocks on the door and me and DH answered. She said 'do you wanna come next door to our party?' (A fucking HOUR and a half into it!!!!!!) I said 'Oh no thanks. We're off out in 10 minutes to my cousins's 30th birthday party.' Then we went out to park for an hour then went to the pub til 9pm LOL!' (My cousin DID have a party but not for 3 weeks. So when that was due I said it was another party.)
Sad and a bit daft, but I was proper fucked off that she has assumed we had fuck all else to do. (Even if we didn't hahaha!') 
And we really enjoyed our trip to the park, and our evening at the pub. 
So NO I would NOT go the wedding OP.
