The younger kids came home from the first day of Totus Tuus camp wearing strings on their wrists. I asked why, somewhat nervously — hoping that no one had pressured them into making some kind of pledge or consecration that they’re not ready for. My seven-year-old cheerfully explained, “Oh, we have to wear this all week, and if we show up without it, we have to sing a silly song.” How cute! I thought. Then the next day, she showed up with a second string on her wrist, this time a green one. She casually explained that these are the liturgical colors, and she could tell me what they stood for. And that, if you forget to wear them, you have to sing a silly song.
