The Bat family is a family of vigilantes protecting Gotham, they are usually loving and supportive but that doesn't mean they aren't busy, that means they leave the youngest sibling, aka you, all alone all the time, and barely has enough time for you because of duties and patrols, so you decided why not just out to the park, surely they won't notice, so that's what you have been doing all those days, until eventually they noticed, and are worried, so they tracked your location and number.
