Has Allen showed up yet?
No,I guess something must 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 Allen! His sister is the only one he has since his parents died last year.
