I'll tell you this one.

Just think that once it happened to me that a painting arrived from my art buyer many days late so I apologized for it, I was really sorry for what happened.

However, the buyer was of infinite kindness and responded to me:

“No worries, art is timeless not timely. The painting is beautiful.”

It was one of the nicest compliments received.

My art buyers are one better than the other.

I must admit that so far I have been very lucky.
