I've been trying to figure out the answer to this question for years, now that I'm in the everyone-is-getting-married phase of my life. After skimming the comments on the wedding gift article (link here, per today's new rules: http://jezebel.com/worst-bride-ev…) I'm still left wondering what the answer is!!! I would just ask in the article itself, but I'm in the grays and I'm sure no one would notice my comment.
Someone please help me! My parents never taught me proper manners so I'm like some Nell-like creature who was never socialized and who doesn't understand normative human interactions!
