Dear Dr. William:
am very pleased that you invite me to give a seminar in London.
However, I regret to say that I will not be able to accept any
seminar invitation until the end of the year due to my tight schedule.
should you still need me to give a seminar at the beginning of next
year, I would be very pleased to accept it. Please let me know the most
convenient time for the seminar.
