They are very old and dear friends. It was always inevitable but I am oddly upset.
I had a mutual friend (she doesn't know them that well at all) over for dinner last night and she told me all about them being engaged, but she'd only heard through a friend of a friend of a friends status update on facebook (phew that sentence was had enough to type let alone read back)
I'm going to theirs this weekend (amazing houseboat on the Avon) and am sure they wanted to tell me in person. They are very private people and I know they would be annoyed their news is spreading around beyond their control.
I won't be able to feign surprise, should I let them know I know?
p.s thank god I killed my facebook account
