For a a lot of our early years, we would innocently go through life thinking we could take people at face value.
If someone told us that we might be at risk of cancer if our hand is as big as our face, many of us took it as serious medical advice and not somebody's else's opportunity to make us hit ourselves.
But alas, we soon learned that not everyone in life will throw straight dice with us and sometimes life itself likes to take its mean streak out on us.
And if these people hadn't learned that already, they certainly know now.
