How can a mother and father not care for their own son??

Tweet

This makes me so sad. I know that my brother-in-law is a grown man. But the way that his parents treat him is just sad. His mom does not want him in their house. He is sitting on the porch in a chair. It is very hot outside, like in the 90s. And his skin is getting all dark and ashy. I know that he needs a shower. It is hot outside and my mother-in-law knows that he is out there, but she will not bother to offer him anything cold for him to drink or to eat. I feel so sorry for him, I really do. When his father discovers that he is at the house, he will run him from the house. He tells him to leave. My father-in-law caught him sleeping in his sister's own car and he made him get out of there. He had a heater rigged up in the car. This was during the winter time. Why not invite him into their house to get some warm heat? My sister-in-law would sneak food to him from time time. She would give him food from her bedroom window. And, if he even comes into the house to get something to drink, my mother-in-law will fuss at him. She won't let him have anything to eat. He never comes inside the house when my father-in-law is there. This is their blood child. I feel so sorry for him. I don't care what he could have said or done to my mother-in-law, but this is no way for a mother to treat her own child!! Can she be so fed up that she could careless about him? My sister-in-law told me that her mom and dad will burn in Hell for treating their son like this. What do you think?
