...than just to be told quietly that it's a small wedding and we're only having a few people and thus not invited at all? To me evening invitation smacks very much of 'we're not very bothered about sharing our day with you, so travel a long way, find childcare, get all dressed up, then have a bacon sandwich and give us a present anyway'
And for context this is one of DH's close friends, was an usher at our wedding, but his fiance doesn't know us very well.
