My future aunt-in-law hosted a shower for me this past weekend, which was wonderful. Her two teenage daughters came as well, and one kept a list of all the gifts while the other brought the presents over. I didn't know that they'd be doing that, which was really nice of them!
Should I write them each separate thank-you notes for helping out at the shower, or should I address the thank-you to all three of them (mom and daughters), also mentioning the gift they got me? I feel like this really has to be common sense, buy my brain is broken at the moment.
