'It’s OK,’ Nicole replied, showing Bradley her drawing. He was relieved to see that her portrait of him looked like the orang-utan’s brother. ‘Looks as if getting facial 36 _ correct is trickier than we thought,’ she joked.

While frustrated at times, Bradley persisted 37 _ his artwork.

By the end of the courses, he had some accomplishments proudly 38 _ in his home, and others that were tossed into the recycling bin.
