It's my 40th in July and having ummed and aahed over what to do, I think I've decided on having it at my house, split into two parts. Afternoon tea at 4pm for the older relatives and those with young babies, then an evening party with music, dancing and drinking starting about 7. Do I send separate invites, or invite everyone to both parties? I was planning on it being family and close friends in the afternoon, then inviting more people in the evening. If people were coming to both, what would they do in between parties iyswim? How would I word the invites to avoid offending those who aren't invited to the afternoon bit? Sorry to be a pleb, I'm not used to party organisation!
