All my parent did was complain. Complained about our home, about friends, about the running of the country. It amazes me how someone who had little money seemed to be an expert in the economy.
Actually it was more a case of wanting more money to be given over and even if that was the case my parent would have complained that it wasn't enough.
Still I got away from that influence, when anyone asks how I am I say 'I can't complain.'
I could, I just see no reason to.
