I'm a bit worried that if I invite people at 4.00 they won't be very hungry, but there will be a lot of food - sandwiches and cakes and cocktails.
Do I change it to a lunch or evening thing? But I feel weird inviting people for lunch or evening and then serving afternoon tea.
Do I make it clear on the invitation that there will be food? 4.00 is a weird time to eat.
How do I do this? How would you do it? What have I not realised?
