I was sitting on a train recently, hearing the woman next to me talking to her mate about her wedding.
The whole tone of her (very one-sided) conversation was about how she expected everyone to dress up for her upcoming wedding, that she was insisting that everyone wore hats, and what a mess Tanya had looked at the last one (yes, her last wedding!), because she wore a blue dress and black shoes, and carried a straw bag, and had her hair in a pony tail, if you could imagine, and she'd refused to by one of the pictures because Tanya was in it too, and she spoiled the picture, and on and on and on.
I thought is was pretty sad that she was so obsessed with how everyone looked, and didn't seem to care about anything else.
In the end I stuck my nose in and said "don't you just want your friends to come and see you be married, and have a good time?"
Which at least had the result of getting her to shut up about it
