Don't bother OP, weddings are invariably shit, especially when you have been somewhat unfairly overlooked.
We've been to three family weddings on DH's side in the last three years, and all the cousins have been bridesmaids (some several times). Apart from one. My dd. She seemed to be the 'forgotten' one every time.
I shan't be forgetting it in a hurry though.
The last wedding we went to, we were standing round at the venue in the afternoon, as you do, chatting away politely to people we didn't know, noticed that loads of people had disappeared and I said "Where's the bride and groom gone?" "Oh," said the person I was talking to, "They're doing the photos. It's just family only though."
We are sodding family and although we went and stood round by where they were taking pictures and I pointedly stood next to SIL/MOB in the watching crowd, the photographer had a massive long list and was calling people out. All the mums & dads, brothers and sisters, aunts and uncles, cousins and old timers, everyone had their photos done with B & G. Not me, dh and dc though. Even though were were aunt, uncle and niece of the bride.
To say I was put out would be the understatement of the century. Especially as dh had been driving about all morning delivering flowers and champagne and transporting random family members everywhere, and dd was the same age as another cousin who was a bridesmaid.
SIL/MOB married all three of her kids off, and every single time dd was overlooked. It isn't even a huge family with dozens to choose from.
So SIL, if you are reading this, that is why we never bought any of the stupidly expensive wedding photos of your three precious offspring. We aren't in any of the family photos. One day maybe, when you are all sitting round looking at them, and someone notices and asks why we aren't in any, you'll realise that you were (and still are) a complete cow.
