Cruelty 1

How can I be so cruel, I only gave dad 350 dollars every month, thinking that 10 per day is enough to sustain him. How did he survive with such little money, I will never know. The last time he asked for money, as usual I would complain that he is using it too fast. Although I later told him that he let me know if it is not enough, I never apologize to him. He mentioned to my mom that he felt embarrassed when his Friends gave him money, I ignored his need for self esteem, he had to endure the suffering of his illness and yet also had to endure my cruelty, the lack of love, the feeling of being abandoned. Only a brave man like him could endure all these unjust. He never reprimanded me, took all in silence and I abused that, I only have interest in my own happiness. How evil can one get?
