Everyone in life has secrets. People hide things that embarrass them, make them feel ashamed, or even just that they don't want people to know.
Many times, some will reveal their secrets to close individuals and those that they trust, but there are those who don't trust anyone and those who keep things closed off forever. Some people keep their secrets for life, that they're going to take to the grave. But, there's nothing quite like sharing them with total strangers online.
