A story from "The Lore and Lure of Hooked Rugs"

I read this the other day. I had to read it again because I couldn't believe it. I am curious what your reaction is to this anecdote.

It was written by Pearl McGown in The Lore and Lure of Hooked Rugs, p. 86. She used this as an example of the good sense and ingenuity of one of her teachers.

"On one occasion colors were changed without the rugger's knowledge. A very beautiful room-sized rug was exhibited one year at Worcester, and when I congratulated the teacher who was exhibiting it, she said, 'It is lovely now, but you should have seen it when my pupil delivered it to me. I had given her instructions for the one remaining flower (multiplied many times in the design). I did not see the rug again until it was completed, and she had made all those flowers of the brightest purple you can imagine.'
'But they didn't seem bright to me,' I remonstrated.
'Of course not,' she replied. 'I wouldn't have exhibited it as it was. I made a weak solution of its complementary dye and vinegar and with a small toothbrush I subdued each flower.'
'But what are you going to say when you take the rug back to her?' I asked.
'Well,' she replied triumphantly, 'I'm going to tell her that Pearl made me do it!'
