>>105887030While it isn't clear what happened to his son's mother, it is clear that Max is all he has in life besides his asshole neighbor Pete. He worked a shitty factory job to support his son, and when he left for college we can clearly see how empty and lonely the house is. It is obviously as over the top as this situation could have gone, but I can bet that any single parent with a kid who just left the house would have similar emotions.
