I will be 40 next year, and we are having major works done to our house and also two big trips abroad so we can't afford to have a big party. I would, however like to do something to mark the occasion. I have finally come up with an "open house" idea, say from midday till late, where people can come any time, stay however long they want and then go home. I will provide food, but nothing huge, so sandwiches, tea, cake and booze. I will also ask some people who are very close to me to make or bring something to add to the food; I know they won't mind, and as I always do this for them I know it won't be a problem. DH however thinks this is unacceptable; he thinks we can't ask people to come a long way for anything less than a sit down meal. I have said I would make the food arrangements clear on the invitation so people have the option of declining to come if they think it's too much effort. AIBU?
