We were invited to friend's daughter's evening do, locally, and chose to go to the church so we felt part of their day. I'd heard all the ins and outs of the organisation for months as I saw my friend a lot during the working week. She apologised for not inviting us to the whole do but numbers and cost meant they couldn't invite everyone. I quite understood and took no offence at all.
The wedding that did bug me though was the invitation to the church, then not to the drinks, canapés and photos, but come to the meal a few hours later.
It was local, but pouring with rain. We all went home to hang around and returned in good time to find everyone seated and already eating. We were told to find our own seats but I insisted on being escorted to them, turned out I was sitting next to the bride. She was mortified and had told the hotel not everyone had returned, but they said they wanted to crack on so the staff could get off!
