My 15-year-old daughter is a really good kid, and I’ve tried to respond to her various experiments with identity in a spirit that’s curious and nonjudgmental, but her latest one has me stumped. Every day, she paints half of her face purple using stage makeup. When this first started a couple of weeks ago I commented that it was an interesting look and asked about it, and she just shrugged and said she liked it. I’ve mentioned it a couple of times since then and she just says it’s not a big deal and acts like I’m weird for asking about it. I’ve been getting questions from other parents about this and I don’t really have anything to tell them. Is this some kind of internet thing that I’m missing? Is she trying to bait me? Her older brother’s wedding is coming up and he and his fiancé think the whole thing is hilarious, but I’d really prefer she not wear it there.
