A childhood belief about money

When I was little, from three to eight years old. I thought we could get as much money as you want from an Automatic Teller Machine. My mum kept on trying to explain to me that "Money doesn't grow in the bank" to me and "Money doesn't grow in trees" to my younger brother and therefore we can only take a limited amount of money from the bank. I slowly began to realise a few years later that my family can only withdraw the money my dad earned from the bank.
