My sister freaked out. She’s still angry and says I violated her trust, and that for the rest of her life when she looks at her wedding pictures of the family together or of me in the background, she’ll know that there’s blue and purple hair under there, and it will infuriate her. I don’t see any problem with what I did. I didn’t want to change my hair color for ONE day in her life, and I even invested in a hair-piece specifically meant to give her peace of mind. I hadn’t considered telling her about the wig beforehand, simply because she was busy and, as long as I showed up with “normal” hair, it should have been fine. How am I in the wrong here? Did I owe it to my sister to actually color my hair for her wedding? I wasn’t even a bridesmaid.
