I Broke My Sister's New Phone

So, I was cleaning my room yesterday and found a box of old marbles under my bed. It brought back memories of childhood, but then I got distracted thinking about how much better the new glass marble designs are now compared to those old plastic ones. Anyway, I was in such a nostalgic mood that I decided to surprise my sister by drawing some illustrations of her favorite character on a couple of marbles. But here's where things get tricky: while sneaking into her room to hide them as a secret gift, I accidentally knocked over her new phone charging on the nightstand. And yes, it was one of those fancy models with the glass screen, totally shatter-prone and expensive. To make matters worse, my sister is really protective of her gadgets because she works remotely from home. I've been trying to figure out how I can fix this without getting caught or having to admit what happened. But every time I think about it, I keep worrying that she'll never forgive me for ruining something so important. Maybe I should tell my parents and let them help cover the cost? Or could there be a way to secretly repair it myself? But really, at this point, I'm just hoping no one notices until after we all go back to school next week. The thought of her finding out makes me feel like I've already been caught.
