When guests come to the house for Thanksgiving dinner, there are a few things that they should do while at the table and a few things that you should do as a host. One of the things that you want to do is to take a dish if you are a guest. You should take something even if the host tells you not to worry about bringing food. Even if it’s a simple pack of rolls or a pie, it shows that you’re thankful for being in the home with family and friends.
Show your thanks to the host by taking your food in a new dish that the host can keep. It’s suitable to take the food in a disposable container so that the host doesn’t have to wash dishes, but it’s a better idea to take what you prepare in a baking dish or bowl. If you have other plans that come up, don’t wait until the last minute to let the host know about them. Keep your plans with the host if something changes in the day or two before the holiday. The host has likely gone to a lot of work to prepare the meal for you, so the least that you could do is show up at the house and enjoy the company. If there’s a true emergency, then that’s different, but if you simply don’t want to go, then that could be a little on the hurtful side to the host.
