Context:It was just a medicine check . Donald got the second half of the spaghetti on in the morning . I got home at noon , ate lunch , then started on the meat loaf patties . I made about 30 patties , cooked them , and shrink wrapped them . In the middle of cooking the meat loaf patties , I tried calling Michael , twice , and when he did n't answer , I drove down to Cathy 's to see if he was home . It was 3:45 pm , and he was no where in sight .
Question What may be the reason why they are so concerned about Michael ?
Answer:
He usually answers his phone and is usually home at that time .
