I think the worst was in 2009, when I suffered a gut wrenching miscarriage with my now husband and, to help myself cope, I bought a mother's ring with gemstones with my birthstone, my husband's stone and the stone of our daughter. One day, a stranger spotted it and said it was pretty and asked if it was a mother's ring and I said it was. She asked which stones were what, so I said X stone was mine, Y stone was my husband's, and Z stone was our daughters. Then the lady asked how hold she was and I said "I miscarried her at XX weeks." The lady said "well, if she's not born then it's not really a mother's ring, is it? The thought is nice I guess, but it doesn't really make you a mother, does it? Now my kids, blah blah blah..."
I could have punched her.
