No one is to blame for your mothers illness. He is being spiteful because he is a penis and does not understand the absurd nature of the universe. My brother in law has just had his mother and father die within 3 months of each other and is nowhere near as spiteful as your brother. He accepts the universe for what it is: absurd. Your brother could do well to understand this before starting his man-bitching like a f- mangina!! PENIS!!!
