It happens to everyone at least once. You receive a holiday present from someone you had absolutely no intention of giving one to. Don’t panic.
When this situation arises, stay calm. Do not apologize profusely. You don’t need to refuse the gift. In fact, you should accept it. Simply say thank you and acknowledge their kindness. Don’t make up an excuse about how you left their present at home, or how you will have it for them tomorrow. Chances are, that will only embarrass you both.
However, it isn’t a bad idea to have an extra gift on hand for the holidays. Keep it simple though, a gift certificate or bottle of wine is perfect. That way, you will have a present if you need one. If you don’t end up using it, you can wine and dine yourself!
