By the time he was 4, Gary Coleman had developed a wit and precociousness that charmed his parents Sue and W.G. "Willie" Coleman. Tragically by his 20s, he was no longer speaking to them.
"Before he was in kindergarten, Gary had an imaginary friend, who he called Kumas," Sue, 67, tells PEOPLE. "If Gary did something bad, I'd say 'Gary, why'd you do that?' and he'd say 'I didn't do it mom, Kumas did it!'"
It was Gary's contagious personality that got him plucked from the Midwest and set down in Hollywood – a move his parents have never regretted, despite their son's longtime struggle with fame.
"He had a God-given talent," Sue explains. "Getting into show business was his decision. We always told him, 'It's up to you, Gary.' We never forced him to do anything. We protected him as best we could."
They saw their son's primetime success as a way to overcome the limitations of his ill health: The first of two kidney failures occurred when he was 5, and doctors warned early on that he may not have a long lifespan.
"We were happy for him, we were so proud," Sue says. "We always worried how he could be self-sufficient in life because of his condition. People said he was forced to work while sick, but you have to understand, Gary was never in perfect health. We were the first to take him home if he didn't feel well."
