Last year, for Christmas, I made little gift bags for my cousins and my aunts. Handmade soap, lotion, etc, and put them into nice organza gift bags. I packed the gift bags into a larger bag by family, so my two cousins and aunt in one bag, another cousin and aunt in a second bag, etc.
When people opened the bag, everyone was very appreciative and thanked me for making all of this. Except for one aunt, who was very unhappy that "her" gift bag had gifts for three people (her and her daughters) in it. She scolded me, "LadySnowdon, you know I don't like to share!" in front of everyone. My cousins interrupted her scolding to thank me for the gift, which did make her shut up.
My aunt comes up with something like this for every single holiday, whether it's scolding people for the wrong present, the wrong presentation, or the wrong food item they brought. Everyone mentally rolls their eyes and thinks, "That's just Aunt for you!"
