I first met Katherine and John at Fabriano in Acquarello 2019. Their friendliness immediately made me feel comfortable with them. After many years without meeting, we saw each other again in 2025 when they visited Warsaw. Together with my friend, the painter Minh Đàm, I had the chance to show them around the city. After six years, it was wonderful to see that they were still as warm and friendly as I remembered.
