Yesterday during work I was talking with one of my work friends who's invited to the wedding. She knows that we're not registered anywhere so she asked me what I wanted.I SOOO wanted to say something along the lines of " A card with cash would be great", but I didn't.I completely drew a blank and what came out of my mouth instead was "Oh, don't worry about. Just come and eat, drink and have a good time"Good etiquette? Other options?
