That there's an undercurrent of cruelty to life that can't be photoshopped or filtered away.
That beauty, looks and the body for men and women wither.
That health, peaceful old age, love and a happy family are not guaranteed to anyone.
That things don't just happen for you because you are good. The horrible secret is that actually selfishness and a disdain for what other people think/feel gets many further.
My mum told me the story of just having had me in hospital and being next to a beautiful Indian woman who had just had her own baby. She had a scar down her cheek and told my mum that she was in an abusive arranged marriage. She was crying and told my mum that this was supposed to be the happiest day of her life, but now she knew she and her baby were truly stuck.
That good things don't always happen to good people.
That some people are truly evil to children, animals, women, men, there isn't always that 'natural kindness' that people are supposed to feel towards living things.
That illness is an insidious, slow decline that robs you of dignity, of hope, of courage, of looks, of hygiene, of independence.
That love is not forever as you lose people you love or they become unwell.
I try to find joy in the day to day now, I still comfort myself with TV shows and movies, I think we all do, but I know that life has a crueller edge and is unfair. I don't think there is much to perfectly presented life's - suffering is indiscriminate.
