A friend had my kids after school this week - primary age - and one of the activities they did was henna tattoos. They now all have an arm and leg of brown tattoos, some swirly patterns, some things like a picture of a lion and an apple. The leg ones look like they have mud (or worse!) splattered. It’s fine - not the end of the world and school are relaxed, but no way would I do this to someone’s kids without permission. Aibu?
