My Sisters

I have 2 sisters; one older than me and the other is younger, older sister is married and has 3 kids, two boys and a girl, she is the best sister I could ever have; she is soft, kind, helpful, smart, patient, and supportive. Her youngest child has down's syndrome; she is so kind and patient to him, she never complains about this that she is taking care of her family including her sick child; I consider her my hero for her strength and determination to study, work, taking care of, and support her family, I would do my very best to make her happy. 
My other sister is the opposite; she is selfish, always complains, never likes her situation, even though she has a much more easy life than my older sister, but she always wants more and more, I love her as my sister, but I never like her attributes.
