You and a friend each recently had a birthday, and although you were out of town for yours, she’s having a party to celebrate hers with a group of your mutual friends. You consider hunting for a gift before you go, but since it’s a large group party you opt not to and assume that it won't be a big deal.
Much to your dismay, when you arrive at the party the birthday girl hands you a huge present. You watch her eyes take you in and realize that she’s noticed you don’t have anything in return. It's completely awkward and you feel like you have to say something. How would you handle this?
