‘And where’s my bag?’ I put down my science book (all I ever seem to do these days is schoolwork) and look blearily up at Mum. I don’t know why she’s asking me. She knows I’ve been sitting here for the last hour. ‘No,’ I tell her. ‘No to which one?’ she says, bending down and dragging her bag out from under the kitchen table. ‘How on earth did it get there?’ ‘No to both. I haven’t seen Alex and I didn’t know where your bag was until you just found it.’ ‘You were virtually sitting on top of it,’ mutters Mum, sounding grumpy. ‘Are you sure you haven’t seen Alex?’ ‘Yes, Mum,’ I say, closing my book. I’m feeling completely distracted now and I’ve done enough for today anyway. Hannah’s coming over in a while and we’re going to start working on our history assignment. ‘What time’s Hannah getting here?’ asks Mum, looking at her watch. ‘Will you be OK on your own until she arrives?’ ‘Mum! Stop worrying. She’ll be here in about half an hour.
