Hello, I have an etiquette question I wonder if you could help with. My husband and I have been happily married for 22 years and together for almost 29 years. We have two children, a girl 19 and a boy 15. Yesterday was my mother-in-law's birthday, and as usual we went out for a family dinner to celebrate. At the dinner my husband's sister who is engaged to be married, presented my mother-in-law with a necklace. The charm on the necklace was of a gold tree. The branches on the tree had 6 birthstones on it. Each birthstone depicted one of 6 family members from top to bottom... my mother-in-law, father-in-law, my husband, his sister, and my two children. My birthstone was not represented at all on this tree. My question is, am I wrong to feel left out of this family tree? I'd appreciate your feedback. Thanks!
