What should I do when having a invitation for dinner at Thanksgiving in a American family?
If they are good people, if you know the purpose of the invitation is good, friendly, your relationship with them is good, I think you can accept that invitation, the gift can be red wine, champagne, chocolate, cake, fruit, or any dish that is made by yourself. You can say that you are very happy to be a part of their Thanksgiving party, thank you so much for their invitation and highly appreciate. Wish you a happy Thanksgiving.
