While it isn't courteous to show up at a holiday party empty-handed, the reality is that many gifts go unused, unopened and eventually end up in the landfill. So this holiday season, bring something perishable. Ask the host or hostess what item you can bring to their party. It can be a good bottle of wine, a tray of cookies or a side dish for their party. No mess, no waste and everyone can enjoy your tasty treat.
