Iknow i (supposed, phone) you yesterday, but i've lost my mobile! i'm sure i hsd it with me when i left work, so i (can't, leave) it on my desk. i suppose i (might, drop) it on my way out or it (may, fall) out of my pocket on the train. or i suppose someone (could, steal) it! what(coul, happen) to it? i dropped it, someone (should, find) it by now.
