Ah, sisters!

Telephone conversation with Sophie yesterday:

Sophie: I woke up in the night a few nights ago thinking "I don't know James's surname"!

Me: It's Smith

Sophie: [high-pitched] Oh!

Me: What?

Sophie: You can't change your name when you marry him. Rebecca Sm*th sounds like the sort of person who would wear really boring clothes!

That's decided that, then!
