I had my bridal shower today. Everything went alright, until it came time to open my gifts. I opened one by one, personally thanking the person upon opening them. It dawned on me then that I hadn't yet opened a certain someone's gift, so i discreetly looked around to see if maybe my MOH missed it when she was handing me everything. Nope. Turns out this certain someone didn't even bring me a gift, not even a card. My mom mentioned to me that I should get started on my thank you notes ASAP, which is something I planned on doing. But here is my question. Do I send a thank you note to the person who just showed up without a gift? What's the etiquette on this? And I was told that the point of a bridal shower is to shower the bride with gifts. Is it considered taboo to show up without a gift or a card?
