So we are having our holiday party Dec 30. It is at one of the department head's houses (the party is only for our specific department), and the invite says "food and drinks will be provided". Usually, going to a holiday party or get together, I would bring a bottle of wine for the host, but I work for a church and know that they do not drink. Should I forego bringing anything altogehter, or is it necessary I bring something? If so, what do you think would be appropriate?
