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.
