Never been as tempted to smash someone's face in as I was whilst shopping in my local supermarket today.  A woman in her early sixties was shopping with her elderly mother.  I'm guessing her mother may have had dementia or possibly she was just, god forbid, old.  I  saw her 3 times and each time she would speak to her in completely louder than necessary clipped tones.  'Stop touching things', 'what are you doing?', 'how many times do I have to tell you?'.  I looked after my mother when she had Alzheimers.  It is tiring, it is testing, it is exhausting, it is everything you might think it is and then some.  What it isn't is a licence to be cruel.  I was mentally begging the daughter to look at me so she could see that her behaviour had been noticed.  I know we are meant to mind our own business, to not judge, to not get involved, but........I hate myself for not having had the courage to say something.
