Simon Au Tak Shing (81) writes, "Clovis Hui (one of my classmates) and I visited Fr Farren at the end of April.   We stayed at Dublin for 4 – 5 days.   Clovis stayed longer than I. 
Fr Farren walked with the walking frame steadily. He could walk a short distance even without the frame.
His voice was strong but memory was not as good as before.
Luckily, he does not feel any discomfort caused by the cancer at the moment."
