My heart leapt in my chest as I clambered up the metal steps of the train. This was it. I couldn't back out now. No way. Not since I'd waited by the letterbox for two whole weeks, silently begging it to arrive. Especially not after I'd dragged mum into Diagon Alley the minute it had slid through the door. I remember how my heart had leapt then, too. In excitement for what awaited me. In joy for what new things I would learn and in relief that it had finally come.
