Agus cannot pick up Didiek at the airport

because

He has to accompany his son in the hospital
Discussion:
Dear Didiek,
I am afraid I won’t be able to meet you at the airport. My son is hospitalized. Please directly come to my house. The key is under the door mat.
                                                              Regards,
What is the message about?
