There's a older couple that love 2-3 houses away from my parents. They seemed like the ideal couple. He was very much the courteous old-world gentleman, she was a devoted wife and stay-at-home mom. Only very recently did we all find out that he's an alcoholic who always had a bottle in his desk at work, and that he'd been beating his wife for years.

Just because a situation looks ideal doesn't mean it is or was.
