You are attending a Holiday Party, what is expected of you? In case you didn't know, you need to bring something considerate and useful for your host(ess). While this may be a total surprise to you, the fact remains that when someone takes the time to host a party and invite you to said party you are expected to arrive with something specifically for the person(s) who invited you.
If you bring a bottle of white wine, put it in the refrigerator, especially if it was chilled when you arrived. better yet, open it and ask if you can fill a glass for a few of your fellow party attendees. If you brought red wine, mixer, chocolates or some sort of dessert which can be set on a counter, put the wine and/or mix in the designated bar area. Place the desserts where it looks like they are congregating. Finally, if you brought flowers, ask the host(ess) if you can go ahead and place them in a vase. Ask where to find the vase, get it, fill it with water and arrange the flowers. Then clean up any ribbon, plastic or spare leaves so that everyone notices the lovely bouquet, not the garbage left from “helping” the host. While all of this may seem like work on your part, think of it as filling the role of a responsible adult. The adults who invited you to their home are busily prepping for fellow party attendees and trying to make sure that everyone has a nice time. Your small addition is appreciated and to be honest an upstanding adult and friend needs to do their part to help and be a good friend.
There are plenty of websites equipped to help a party guest discover exciting contributions for a host of a party. One caution, however, is to make sure you give something the host will appreciate. You are attending a party and your host(ess) is creating a party atmosphere. A bottle of wine, flowers, side dish, six-pack of beer or anything that will be utilized at said party will be most appreciated.
Hostess gifts are a thoughtful way for you to let the inviter know you are flattered they included you in the event. So bring a considerate present and have some fun.
