A long time ago (2-3 years), one of my friends invited me to her wedding in our hometown. I was away across the country at school and couldn't go, but I sent them a nice gift from their online registry. I never received a thank you card, which surprised me because this bride is very polite and really seems to care about etiquette. I never asked if they received my gift because I didn't want to be impolite. Then I started wondering if they even realized the gift was from me--gift wrapping wasn't available for this particular item online (because it was backordered and had to be sent from a different warehouse or something), so maybe it's possible that it didn't include the name of the person (me) ordering it. I started feeling bad about it and thinking they might not have even realized I sent them a gift. Should I have asked if they received it? I realize it was forever ago, and I should probably just forget about it, so is too late to ask about it now? I just really wanted my friend to know that I cared about her wedding even though I couldn't be there.
