DH and I have been invited to a wedding which is in a few weeks. We are day/evening guests. The wedding is of a close colleague of mine and I was touched to have an invite to the ceremony/whole wedding. I asked my parents when we had the save the date if they would look after DS1 and DS2 for the day so we could go. My mum asked me this week what time the wedding will finish and most likely we will be home at 6pm?(!) It’s a 2pm ceremony and it’s a 30 minute drive for us. So that would mean leaving at 5.30...probably still be eating our main course! I’m gutted 😞 Tried to broach the subject again today and I said it’ll probably be later than six as there will be speeches/cake cutting and we fancy a 💃 dance. She says “do you’ll be home at 7 then?” I feel like it would be rude to leave so early and we literally never go out or have childcare for anything. Not planning on staying til midnight but was hoping to stay until at least 9.30/10. How do I broach the subject and ask them to stay later? They are very set in their ways and don’t like being away from their own house/out of routine. They don’t drive but we’ve offered to pay for a taxi home for them. They are of the era when you got married, had a meal then the bride and groom went off into the sunset...
