I found out that my father who lives by himself is allowing a 60 year old man who he met in the park, who is homeless to come to his house to eat and take a shower. He is also going to the grocery store to buy him food. The man states that his wife died about 6 months ago. My father told him that I would not approve of this and had to stop. The man told my father that this is his house and he can do what he wants to do. This man has had 25 criminal charges and/or convictions.
