Has Alan shown up yet ?   Nope . I guess something might have come up .   I wonder what happened .   I don't know . I hope it's nothing serious .   Last week his sister was admitted to the hospital .   Oh ? What happened ?   His sister had a car accident last week .   Is she fine now ?   She is still in a coma .   Oh , poor Alan ! His sister is the only one he has left since his parents died last year .
