Oh Louis, you'd only spend that money on your own ever-expanding ass anyway. You'd only allow it to end up going towards you to stuff your fat gob, because that is what toxic obeasts do. And what's to say, even if your mother did manage to procure a ham by some means (extremely unlikely it will be through you) that you won't end up devouring the whole thing through a paroxism of pure obeast gluttony?
For there is the obese; those that are fat through emotional issues or cultural bad habits and the ever present availability of high caloric food, but these people are still considerate of others and even try to be decent people.
Then there is the obeast, the unrepentant and revolting gluttons that only care about themselves, and siphon off finite resources to feed their appetite at the expense of others.
You are the Obeast.
Your mother is doing you a grave disservice by not making an ultimatum for you to get a real job, because great, great odds are, you'll end up homeless when she passes. That's what eventually happens to jobless coddled manchildren still suckling on Mother's teat, because she won't be around forever. And I doubt your stepfather will tolerate your ass either, especially because he's getting old himself and would not tolerate an annoying jobless obeast sitting at home endlessly siphoning off his own money for it's own parasitic gluttony.
In other words, you fail through your own hand, though your Mother loaded the metaphorical gun, it is actually you that is right now, pulling the trigger. You won't likely have a good future, because you seem to be too unwilling to look beyound your creature comforts to change.
